[SALT eNews] RSS Longslit Spectroscopy Science Data Products Now Available

Dear SALT Community,

We are pleased to announce that the RSS science data products for normal and frame transfer longslit spectroscopy exposures are now available! As of observation date 1 August 2024, these science data products have been included in the daily data distribution. Additionally, all normal and frame transfer longslit spectroscopy exposures dating back to semester 2015-1 (observation date 1 May 2015) have been reduced and are accessible to PIs.

The available products include:

  1. 2D wavelength calibrated and rectified reference (arc) exposures.
  2. At minimum, 2D bad pixel replaced, cosmic ray cleaned, CCD gaps filled, wavelength calibrated, and rectified object exposures.
If the object exposures have accompanying flat field exposures (or if an archival set exists with the same instrument configuration), the object exposures will also be auto gain corrected* and flat-fielded.

For more information, please follow this link.

Sincerely, The SALT Astronomy Operations Team
---

*The electronics of the RSS CCDs may cause slight variations to the routinely obtained gain levels used for gain correction in the primary reduction. An auto-gain correction is applied to ameliorate any significant changes in gain levels.

[SALT eNews] Fwd: Reminder of SALT proposal dealine for 2024-2 semester - 26 July 2024

Dear SALT Community,

This is a reminder that the deadline for SALT proposals for the 2024-2 semester is this Friday , July 26 , 2024, at 18:00 SAST (16:00 UTC). Please find the full announcement with relevant links below.

Additionally, we kindly ask PIs with accepted 2024-1 SALT proposals, to consider submitting more targets that are suitable for observation under poor weather conditions (thick clouds, high seeing constraints) and/or bright conditions. The queue for these conditions is currently sparse. We remind PIs that P4 time for approved programs is free and unlimited, making it ideally suited for observing bright targets under poor weather conditions.

Kind regards,
Danièl

[SALT eNews] DEADLINE EXTENSION: SALT Call for proposals for semester 2024-1

Dear all,

As many of you know, we have been experiencing technical difficulties with the network at both the SAAO and SALT recently, which are having a negative impact on the proposal preparation and submission process. We have received several new proposals and progress reports, but we are aware that many of you are struggling.

As a result, we have decided to extend the proposal deadline by one week, to Friday 9 February 2024 at 18:00 SAST (corresponding to 16:00 UCT).

Please share the news widely within the SALT community. For the time being, we request that you also please also cc your liaison SA or myself whenever you send an email to salthelp.

I include below the original call as a reminder, with the updated call deadline to prevent confusion.

Apologies for the disruptions.

Sincerely,

Encarni on behalf of SALT Astronomy Operations

[SALT eNews] SALT Call for Proposals for semester 2023-2

Dear Colleagues,

We are now accepting SALT Phase 1 proposals for the period 1 November 2023 - 30 April 2024 (2023 Semester 2).

The Phase 1 proposal deadline is Friday, 28 July 2019, at 18:00 SAST (corresponding to 16:00 UTC).

This proposal call is for SALTICAM, RSS and HRS. All details of the status of specific instrument modes are available in the Call for Proposals link below, including changes from previous semesters.

NIRWALS proposals are not being requested in this call. The commissioning and integration of NIRWALS into SALT is progressing well, albeit at a slower pace than anticipated; the instrument+telescope is not yet ready for a regular science call. SALT and the NIRWALS team would like to work closely with interested PIs to start NIR science during semester 2023-2 as soon as the instrument is ready, likely in early 2024. Please get in touch with the commissioning team via salthelp@salt.ac.za if you are interested in getting involved during the early science period. We will contact PIs who have submitted NIR proposals in previous calls. In addition to engineering time, up to 30 hours of DDT will be made available for early NIRWALS science.

Proposals requesting brighter Moon or poorer seeing conditions are particularly encouraged, as we have noticed a significant drop in such proposals over the last few semesters which is leading to a very uneven observing queue (i.e. observing gaps and tight competition in the best conditions).

Instructions, software, and other information about proposing for SALT can be found on the SALT website.

Call for Proposals, including link to information document: http://astronomers.salt.ac.za/proposals/

[SALT eNews] SALT Proposal Deadline Extension to Friday 3 February + NIRWALS update

Oto oryginalna wiadomość:

Dear SALT Community,

We are extending the SALT phase 1 proposal deadline for Semester 2023-1 by a week, to avoid the clash with the JWST deadline. Therefore, the new deadline is Friday 3 February 2023 at 16:00 UT.

We would also like to take the opportunity to give you a brief NIRWALS update:

As many of you already know, South Africa is subject to scheduled rolling power-cuts and these have been getting progressively worse (longer and more frequent) over the past few months. Since the NIRWALS instrument is extremely vulnerable to steep temperature gradients, the danger posed by the worsening power situation has led to delays in cooling the instrument to its operating temperature. This, in turn, has knock-on effects on the commissioning schedule. The instrument enclosure is being cooled this week and the hope is that we will soon be able to continue with the commissioning process that was planned for last November. Early on-sky data in October 2022 indicate NIRWALS performance is good, however, there are still unresolved technical risks concerning the fiber instrument feed that will not be understood until Feb/Mar of 2023 and other telescope+instrument systems that have not yet been tested. Consequently, shared-risk observations with the instrument in the 2023-1 semester may be delayed, but we will keep would-be users posted as the situation evolves.

Cheers,

Encarni on behalf of SALT Astronomy Operations and the NIRWALS PI

This proposal call is for SALTICAM, RSS, HRS and NIRWALS. All details of the status of specific instrument modes are available in the Call for Proposals link below, including changes from previous semesters.

Please note that NIRWALS commissioning has not yet been completed, so it is again being offered on a shared risk basis.

Proposals requesting brighter Moon or poorer seeing conditions are particularly encouraged, as we have noticed a significant drop for this group the last two semesters which is leading to a very uneven observing queue (i.e. observing gaps and tight competition in the best conditions).

Instructions, software, and other information about proposing for SALT can be found on the SALT website.

[SALT eNews] SALT Call for Proposals for Semester 2022-2

Dear Colleagues,

We are now accepting SALT Phase 1 proposals for the period 1 November 2022 - 30 April 2023 (2022 Semester 2).

The Phase 1 proposal deadline is Friday, 29 July 2022, at 18:00 SAST (corresponding to 16:00 UTC ).

This proposal call is for SALTICAM, RSS, HRS and NIR. All details of the status of specific instrument modes are available in the Call for Proposals link below, including changes from previous semesters.

There are three major changes to highlight in this call:

1 - The NIR Integral Field Spectrograph is being offered for the first time, on a shared risk basis. The instrument is being installed at the telescope and it is expected to be commissioned during August/September. A document has been prepared by the NIR PI (link below) with the expected performance of the instrument to enable our users to estimate their time requests and the technical feasibility of their proposals for this phase 1 call. Please note that the phase 2 for this instrument will have its own separate deadline, which will be communicated to everyone once the instrument performance characteristics are known and the tools are ready.

2 - The RSS grating PG0300 will be permanently replaced with the new PG0700 grating.

3 - The SALTICAM imaging overheads have been increased significantly, to match the actual telescope performance.

Please submit your proposal via the SALT Principal Investigator Proposal Tool (PIPT), but please wait a couple of days if you plan to use the PG0700 grating on RSS or the NIR for the updated PIPT to be released.

Instructions, software, and other information about proposing for SALT can be found on the SALT website.

[SALT eNews] SALT Feedback

Dear SALT Community,

We at SALT would like to improve our service to the SALT Community. In order to do this, we need your help: we need to know where we are dropping the ball and what would be most useful to work on. So we have prepared a simple anonymous questionnaire with NO compulsory answers to learn about any issues you’re having using SALT:

https://forms.gle/7qVgm4zu77e9hLch6

We will really welcome all of your answers - anything goes, as long as it doesn’t involve making SALT fully steerable!! ;)

It would be great if you could submit your responses by the end of the following week, Friday 10th June.

Thanks!

Upcoming SALT shutdown dates

Dear SALT PIs and Co-Is of 2021-1 proposals,

As mentioned in our Call for Proposals and, more recently, in our August SALT Newsletter, SALT is having a short shutdown in October. The main purpose of the shutdown, together with a description of the various tasks, was discussed in an article in the newsletter (https://www.salt.ac.za/wp-content/uploads/2021/08/salt_newsletter_202109.pdf). As an update, we can now confirm that the RSS optics replacement will not happen during this shutdown.

We have now finalised the dates as follows:

10th October - last observing night.

11th October - shutdown begins.

~18th October - on sky re-commissioning and beginning of observations with HRS and SALTICAM ONLY.

~26th October - RSS on-sky re-commissioning.

~29th October - normal operations.

Please note that these dates may shift slightly, depending on how things go.

As always, please do not hesitate to contact us (salthelp@salt.ac.za) if you have any questions.

Regards,

Encarni

[SALT eNews] SALT Mini-Tracker science discussion

Dear SALT users

Please join us for an open discussion about "SALT Science with four Mini-Trackers" on Tuesday, 13 July at 15:00 SAST (13:00 UT):

https://saastrnomical.zoom.us/j/94552392231?pwd=by9HTzR3K2xpMUxkT0xTQzhoYTJ6Zz09

Before the meeting, we would like to invite you to think expansively about this concept that is being explored, by which SALT could be augmented and used to provide spectroscopic observations of thousands of additional targets per year, even while executing its normal observing queue...

The idea is to employ multiple “mini-trackers” (MTs) to take advantage of SALT's spherical primary mirror's enormous (35 degree diameter) uncorrected field of view.  These deployable devices, each with patrol fields of 100 square degrees, would be able to range around the focal sphere to access additional targets while conventional SALT observations are made with the main tracker.  A suite of up to four MTs would therefore effectively serve as a set of individual four-to-six-metre mini-SALTs, each equipped with a low-resolution spectrograph that would likely be fibre-fed.  These "telescopes" would be additionally constrained in terms of their track times and the fields they can access due to their dependence on the main tracker, but the simpler spherical aberration corrector optics would increase their throughput.

The main MT science case centres on transient follow-up for the Rubin Observatory and broader time-domain science.  However, we need to be aware of other potential opportunities that may exist and we would particularly like to get a sense of the sorts of targets (total number, sky density, brightness range) that other science areas may provide for the MTs.  An ideal project would include a vast pool of targets brighter than 21st magnitude distributed all over the sky, though only a small fraction of the total pool could be expected to be observed.  Repeat visits would also be quite unlikely with the MTs, since their patrol fields would be governed by the main tracker observing the normal SALT queue.

Please see the attached PDFs for additional information and feel free to share this message with your networks as you consider the various kinds of science that might be pursued with such a system.   If you have any specific questions before the meeting, please feel free to contact us via salthelp.

We look forward to seeing you on Tuesday 13 July!

Kind regards

The SALT Team

[SALT eNews] Launch of the SALT Data Archive: 10th July at 13:00 SAST (11:00 UT)

Dear SALT Community,

We are pleased to announce the launch of the SALT Data Archive tomorrow 10th July at 13:00 SAST (11:00 UT): https://ssda.saao.ac.za

The SALT Data Archive currently contains data from 1340 proposals from 2011 onwards, of which 926 are public. Public data will be available to search anonymously and also to download. Proprietary data can also be accessed by PIs and Co-Is of the relevant proposal via the SALT Data Archive, but this will require authentication (using your SALT Web Manager credentials). 

PIs whose data will be publicly available should have received an email from SALT on the 12th June containing instructions on how to extend their proprietary period (if needed). Please get in touch with us today if you are concerned and did not receive our email. 

The SALT Data Archive is the first part of a larger SALT/SAAO collaboration. It is envisaged that public SAAO data from the other telescopes will become accessible from this portal in the near future - stay tuned!

Cheers,

Encarni (on behalf of SALT Astronomy Operations)

[SALT eNews] SALT Gravitational Wave Event Proposals


Dear all,

As you may already know, LIGO/Virgo came back online on Monday, 1st April 2019. SALT has set aside some time for proposals covering gravitational wave events, which can be submitted by any member of the SALT partnership.

How to submit a gravitational wave event proposal

If you are a member of the SALT partnership, you need to use version 5.3 or higher of the PIPT 

Contrary to Director’s Discretionary Time proposals, you do not have to get prior approval before submitting the proposal.

If you do not belong to a SALT partner, please contact salthelp@salt.ac.za and we’ll gladly put you in touch with our gravitational wave event group members.

Receiving notifications and commenting on proposals

A notification is sent out to a dedicated mailing list whenever a gravitational wave event proposal is (re)submitted and/or comments are sent for this proposal. In order to sign up on this mailing list, please go to

https://www.salt.ac.za/wm/GW/

and sign up.

For those of you with iphones, there is a cool free iphone app on the appstore called “Gravitational Wave Events” (developed by Kramer&Kramer Software, not by us!) that will chirp at you whenever there is an alert!  

More details

We have set up a webpage with more detailed information about the process:

And please also refer to the policy document for more details. 

As always, please don’t hesitate to email salthelp@salt.ac.za with any questions you might have.

Cheers,

Encarni on behalf of SALT Astronomy Operations

Dear SALT Community,

As mentioned already in our newsletter, we at AstroOps really wish to improve our service to you - and we really need your input. Please give us a few minutes of your time to tell us what we do well and where you think we need to improve.

We are all suffering from survey overload, so all of our survey questions are optional - you only need to answer those questions you want to answer. And at the end of the survey, you will have the option to enter a lucky draw for one hour of P0 time for SALT!

Please find the link to the survey here:

https://docs.google.com/forms/d/e/1FAIpQLSejnGQcJlkwKhg37x-05oAM4ycpJJHyB96BumXP_qywpnhHWA/viewform

SALT Status January 2016

Dear SALT users,

please find our first SALT status update for 2016 attached. A text-only version follows below as well.

- Reminder of Phase-1 deadline for 2016-1: Friday, Jan 29th
- Updated PIPT manual
- Record breaking weather and seeing
- Polarimetry update
- Fabry-Perot update
- Upgrade projects and 2015-2 targets
- Laser Frequency Comb update
- Press release: Brightest ever Supernova
- Science papers


REMINDER OF PHASE-1 DEADLINE FOR 2016-1

All PIs are reminded of the deadline at 18:00 SAST (16:00 UTC) this Friday, Jan 29th. Please refer to the detailed information in the Call for Proposals: http://astronomers.salt.ac.za/proposals/


UPDATED PIPT MANUAL

We are currently updating the PIPT manual. The new version so far covers the general proposal creation process as well as the various phase 1 forms. The manual is available both as html (http://pysalt.salt.ac.za/pipt-manual/html/pipt-manual.html) and pdf (http://pysalt.salt.ac.za/pipt-manual/pdf/pipt-manual.pdf).


RECORD BREAKING WEATHER AND SEEING

As much of South Africa is grappling with drought, November and December of 2015 saw extremely good weather in Sutherland, astronomically speaking. The weather downtime of 21% at SALT in the month of December was the lowest ever since SALT records began. The seeing was also very good, the intrinsic V-band seeing at zenith occasionally staying sub-arcsec for hours at a time. The picture shows a field in the Large Magellanic Cloud taken during a SALTICAM science observation for Warner 2015-2-SCI-033 with approximately 1.2" sizes of stars on the detector.

The weather in January in contrast has not been very good. Nevertheless, at this point, with about 45% the semester 2015-2 behind us, nearly half of allocated P0-P1 time has been done, as well as about a third of all P2 time.


POLARIMETRY UPDATE

As described in the Call for Proposals, commissioning of the RSS Polarimetric modes has been progressing, and we accept proposals for 2016-1 for a limited mode: point-source or compact object targets for linear long-slit spectropolarimetry. PIs interested in other modes are encouraged to let salthelp know of their intentions for the purpose of prioritizing further commissioning.

However, we have recently uncovered a potential problem in the RSS detector (PDET) electronics making accurate polarimetric signal determination difficult below approximately 0.3% level. The problem is being investigated, and while we hope a solution is found before the start of 2016-1 Semester in May, users needing this accuracy should be aware of this potential limitation.

For now, we strongly recommend sticking with the Faint/Slow detector setting, and obtaining repeat measurements to assess systematic error.


FABRY-PEROT UPDATE

The dual-etalon High Resolution (HR) mode has been tested on-sky, but is still not in routine use due to instability in the relative alignment of the two etalons. We have now traced the drifts to changes with temperature. Further tests are underway, but unfortunately it is not clear at this stage when a successful fix will be ready. We sincerely apologise for the inconvenience to all PIs affected in the current semester. You may contact your liaison astronomer if you have other options for your blocks, rather than wait for the fix.

Though we are hopeful, we cannot guarantee observations until commissioning is finalized. We will accept new FP/HR proposals for 2016-1, but the PIs should understand the uncertainty. In the Call for Proposals we suggest including a back-up plan, if possible. We will update the FP users and the TACs in late February during the technical reviews of proposals about the dual-etalon status.

As described in the Call of Proposals, the FP/LR and TF modes are in normal use, while MR is currently off-line and is not offered for 2016-1.


UPGRADE PROJECTS AND 2015-2 TARGETS

There are many ongoing technical upgrade projects at SALT. The most recent SALT schedule has the active primary mirror alignment system (SAMS) integration and testing happening March onwards, an RSS service with up to 4 weeks of telescope downtime in July/August during 2016-1, and a tracker upgrade during 2016-2. Especially exciting is to see what SAMS will do for SALT image quality.

The SAMS work does not involve significant telescope downtime, while we had originally scheduled a 4 week shutdown during the current 2015-2 semester. Since progress with science programs has also been good, it is possible that gaps will develop in the queue in March and April. We thus encourage users whose science allows it, to update lists of optional targets in a given time allocation for the latter half of 2015-2, or replace targets which have set with ones still visible.


LASER FREQUENCY COMB UPDATE

As reported in our previous status update and described in http://www.salt.ac.za/news/laser-frequency-comb/ we will likely be doing HRS on-sky tests using a prototype laser frequency comb (LFC) in the middle of this year. These instruments provide an incredibly precise method to calibrate spectroscopy using tens of thousands of lines with well known wavelengths. While the test is mainly an engineering project, it may be possible to do some limited science observations. No separate proposals are called for this purpose, but anyone within the SALT collaboration with interest and ideas on how to make use of the capability on HRS in the short time period the LFC is available, is encouraged to contact us at salthelp@salt.ac.za, preferably by the end of February.


SALT HELPS TO UNVEIL A RECORD-BREAKING COSMIC BLAST

Saurabh Jha, from Rutgers University, obtained spectroscopic observations of ASASSN-15lh with SALT that led to it being identified as the most luminous supernova ever seen! At a redshift of z = 0.2326, ASASSN-15lh reached an absolute magnitude of Mu,AB = -23.5 ± 0.1. The results were reported by Dong et al. in a recent Science paper, and the story has been mentioned in several major media outlets.

LA Times article: http://www.latimes.com/science/sciencenow/la-sci-sn-huge-supernova-20160114-story.html


SCIENCE PAPERS

The total number of refereed papers using SALT continued to climb, reaching 36 for the calendar year 2015. The full list is available at http://astronomers.salt.ac.za/data/publications/

We strongly encourage SALT users to inform us of their papers making use of any SALT data, and to please adhere to the Acknowledgements policy found under the link above. It will make keeping track of the papers much easier. The SALT Board has also requested that authors using SALT data make an effort to make the source of their data as visible in their papers, e.g. by mentioning SALT in the title, if appropriate, or in the abstract.

SALT papers found from ADS after the previous SALT update sent in late October are listed below. These articles include the first one which has used published HRS data.
