2012-2-UKSC-003 (T Pyx; Maxwell), bit only time for one spectrum
2012-2-DC_RSA-001 (PSN J0949-4754; Fesen & Milisavljevic) ToO
2012-2-RSA_OTH-002 (NGC2917; Kniazev) only option in bad seeing

SALT MeerKAT collaboration meeting

On 5 November, the SALT-MeerKAT collaboration meeting was held at the Pineland offices of SA SKA.  The meeting looked at the interactions and potential collaborations between the large astronomy facilities available in South Africa including SALT, MeerKAT, and HESS.   It brought together members of the different communities to discuss current and future directions of the different projects.   Talks for the meeting and the programme for the meeting have been made available for those interested and weren't able to to attend.   The meeting had some interesting and exciting results and one of the main outcomes was the formation of a group to explore future capabilities at SAAO to support the large key MeerKAT science projects.

A new SALT asteroid publication

A manuscript describing the physical and dynamical characterization of a Near Earth Asteroid (NEA; 190491 aka 2000 FJ10) has recently been accepted for publication in A&A. Photometric data were obtained at SALT, which were combined with photometric and spectroscopic data taken at other telescopes. An absolute magnitude of 21.54 +/- 0.1 was derived, equating to a diameter of 130 +/- 20 m – in the transition zone between a gravitationally-bound rubble pile and a monolithic body. The data suggest that this is an S-type asteroid, which means that it is unlikely to be primitive. Numerical simulations of the NEA's orbit were carried out in order to investigate its dynamical history and predict future locations. The large size of the NEA, combined with its slow rotation (>2 hours) and its orbit, make it a suitable candidate for a human mission. Within the next one hundred years, the optimal launch window was found to be 2047-2059.

Tolis Christou (Armagh Obs., UK) lead the effort. The work involved researchers from a range of international institutions, including A. Mickiewicz University in Poland, the South African AStronomical Observatory, the University of Arizona in the USA, and the University of Kent and Queen's University Belfast in the UK. A copy of the article is posted online at http://arxiv.org/abs/1210.3486

Figure 1. Lightcurve of 190491 from SALTICAM in the r' filter (bottom) and an SDSS comparison star (top). There are no periodic variations during a 20 minute period with peak-to-peak amplitude > 0.05 mag. The slope in the linear fit is insignificant, and the scatter of the points is caused by residual effects of the flat fielding procedure.

SALT Status Update for October

================================================
Recent Papers from SALT
================================================

Apostolos Christou at Armagh Observatory in the UKSC along with Tomek
Kwiatkowski and Magda Butkiewicz from Adam Mickiewicz University from
Poland and Amanda Gulbis from SAAO/SALT (NRF) recently published a
paper on the physical and dynamical characterization of nearby Earth Asteroid 
NEA (190491) 2000 FJ10.  They used imaging observations from SALT
along with observations from other telescopes to determine the
characteristics of this asteroid.   Due to its characteristics, this
object may be a good candidate for future human space missions.
More details can be found here: http://arxiv.org/abs/1210.3486

================================================
Science at the Board meeting
================================================

The SALT board meeting is quickly approaching (5-9 Nov)!  The first
two days of the meetings includes workshops on MeerKAT and SALT and
Science with SALT, and then followed by the regular board meeting.  We
will try to post as much as we can on the SALT website and blog, but
if you would like anything presented or to share anything with the
community, please send it along either to your board representative,
email it to sa@salt.ac.za, or post it on the SALT Science wiki:
https://sciencewiki.salt.ac.za/ (you can use your WM username and
password to log in).  We know there have been many great proposals
observed so far and it would be great to hear updates on how they are
going!

================================================
Phase II deadline
================================================

Just a quick reminder the Phase II deadline is Oct 31!  As soon as the
proposals are finalized and reviewed by your SA, they will go directly
into the queue!

================================================
Updates to the PIPT
================================================

If you want to copy blocks from an old proposal to your current
proposal, you should upgrade to version 2.8 of the PIPT, which lets
you do this in an easy manner. See the Phase 2 FAQ for details:
http://www.salt.ac.za/observing/proposing-for-salt-observations/phase-ii-frequently-asked-questions/


You should also consider upgrading if your block lengths exceed 90 %
of the maximum available track length.

However, submitting your proposal with version 2.71 of the PIPT is
still possible.


================================================
Slotmode imaging on RSS
================================================

Despite SALTICAM not being available, high speed imaging can still be
done with RSS.  Observers who proposed for SALTICAM slotmode
observations for next semester can switch their configurations to use
slotmode imaging with RSS.  This mode was successfully tested out in
September and imaging can be done either with a clear filter or with
any of the existing narrow band filters.


================================================
RSS Slotmode Timing
================================================

A series of experiments were carried out to investigate the absolute
and relative accuracy of timing for RSS slotmode. An LED was placed
into the lightpath and was triggered by an independent GPS. The header
times of the slotmode images were compared with the start time and
pulse interval from the GPS.  The results indicated that the relative
timing is good to within the measurable accuracy (half an exposure
time, which was on the order of hundredths of a second) and that the
absolute timing was late by seven exposure times.  Previous tests
using SALTICAM slotmode showed the same effect on the header times
were in fact the readout times rather than the exposure times,
effectively neglecting the time required to transfer through the
masked region.  A timing correction for slotmode data from both
instruments is available in the nightly build of PySALT.

================================================
Updates to PySALT
================================================

We are starting to prepare for the next major release of PySALT, but
the nightly builds now has much new functionality that will be useful
to test out!  This includes reduction tools for SALT multi-object
spectroscopy, fixes for the slotmode timing, new tools for basic CCD
reduction, and general code updates.  Please download and try out the
nightly build and let us know of any thoughts.  Nightly Build:

frustrating night with only one block accepted. abysmal seeing during the first half gave way to steady seeing that was at least mediocre in the 2nd half. however, a slew of technical problems slowed things down considerably. first the primary mirror and then the RSS slitmask mechanism. several PCON lockups happened over the course of the night, sometimes at very inconvenent times.

on the bright side, my calsys script was fleshed out and tested further. it can now query RSS and configure calsys for flats automatically based on my recipe from the wiki. selecting a lamp will coordinate insertion of cal screen, selection of stage, and turning on of lamp into one command.

"Some of my pleasantest hours were during the long rain-storms in the spring or fall, which confined me to the house for the afternoon as well as the forenoon, soothed by their ceaseless roar and pelting; when an early twilight ushered in a long evening in which many thoughts had time to take root and unfold themselves.
...
Men frequently say to me, "I should think you would feel lonesome down there, and want to be nearer to folks, rainy and snowy days and nights especially." I am tempted to reply to such -- This whole earth which we inhabit is but a point in space. How far apart, think you, dwell the two most distant inhabitants of yonder star, the breadth of whose disk cannot be appreciated by SCAM or RSS? Why should I feel lonely? is not our planet in the Milky Way?"

Summary
----------------------------------------------------------------------


night mostly lost to wind, clouds, humidity, and light rain. conditions cleared after midnight and humidity dropped significantly after 0300. opened and tried to get some data, but the quality of the alignment was poor and changed very quickly. managed to observe one block for 2012-1-RSA-014 which is better than nothing. took a lot of FP engineering data to help characterize the erroneous header issue. also helped train brentski how to do FP.

Dome on the Range (abridged)

Oh, give me a dome where the Springbok roam
Where the Astronomers and the Humidity fight;
Where seldom is heard a demoralizing groan,
And the sky is not cloudy all night.

Chorus:
   A dome! A dome!
   Where the Astronomers and the Humidity fight,
   Where seldom is heard a demoralizing groan,
   And the sky is not cloudy all night.

Oh! give me a spectrum where the exquisite planetary nebulae
Send their light in strong emission lines,
Where soareth along the majestic Verreaux's eagle,
High above the Cape's prized vines

   Chorus

How often at night, when the heavens were hidden,
With the bane of the Ridge Cloud
Have I stood here amazed, and asked as I gazed,
Where the hell are our stars?

   Chorus

The air is so pure and the breezes so gale-force,
The zephyrs so balmy and light,
That I would not exchange my dome here to range
Forever in azures so bright.

Summary
----------------------------------------------------------------------


thick high clouds in the first half of the night gave way to clear skies and high wind in the second half. humidity spiked during morning twilight as a harbinger of ridge cloud to come tomorrow night. temperature dropped almost 13 C over the course of the night. seeing was good at times, but high winds prevented an alignment good enough to take advantage of it. IQ was so dire at the end that CAL_SPST and a P4 were the only viable options. ultimately completed 5 blocks and rejected two others. fabry-perot was again shown to be compromised by software bugs.

frustrating and unproductive night with cirrus and thick haze and numerous technical issues. seeing was steady, if unspectacular. lost much of the first half to some weird PCON bugs that prevented us from successfully taking any fabry-perot data. lost another hour each to alignment issues and the cable wrap under the structure. managed to get some data towards the end, but the clouds steadily thickened as well.

finally worked dusk to dawn. the southeaster and northeaster fought an epic battle early on and left heavy turbulence in their wake. seeing in excess of 5" at times and highly variable. the northeaster was eventually victorious and the seeing settled down to 1.5" or better later in the night. unfortunately, lost almost 3 hours of the good part of the night to primary mirror/SPS problems. observed 7 blocks with 5 accepted. also caught up with all outstanding CAL_SPST.

very stable night with good seeing start to end. with the exception of a few blips of 1.5-1.7" the seeing was 0.8-1.2" the entire time. mostly clear as well with some light cirrus passing through at times. mirror alignments worked much better tonight. thanks to hitesh for helping out over the phone at the beginning.

a total of 10 blocks accepted plus another couple rejected. could have done more if there were more programs with southern objects. almost everything in the 2nd half was clustered on the equator within 25 deg of the moon. not ideal. did acquire some pointing data which showed good repeatability all around the vis strip, but with a large offset from the RSS field center.

first half of the night was breezy with come and go cirrus. winds picked up in the 2nd half and closed us down eventually shortly after 0300. only successful science data was FT spectroscopy of V2301 Oph for DoD. attempted a couple of FP targets, but bright moon and poor IQ scuttled them. got full sets of FP calibration data for the entire H-alpha region.

mirror alignment was once again a struggle and sucked up significant time during both attempts tonight.

SALT Status Update for August 2012

=======================
Recent Science Results
=======================

SALT science results are starting to show up on the arXiv, and here
are some of the most recent:

In http://arxiv.org/abs/1207.2152, Dan Milisavljevic et al. monitor
the time evolution of SN 2011ei, one of the least luminous SNe IIb or
Ib observed to date.

In http://arxiv.org/abs/1207.4357, M. Sharina et al. report the
discovery of a new carbon star near the center of the low-metallicity
globular cluster NGC 6426.

In http://arxiv.org/abs/1208.1347, Brian van Soelen et al. use SALT
data to help model the properties of PSR B1259-63, a gamay-ray binary
system consiting of a 48 ms pulsar obiting a Be star.

=======================
SALTICAM UPDATE
=======================

SALTICAM is currently suffering from an array of maladies that almost
completely preclude it from doing any useful science.  It is still
useful as an acquisition camera, but even that is significantly
degraded.  Its filter magazine system is still unreliable and prone to
jamming.  Work is ongoing to design a long-term fix, but in the
meantime a single filter is pre-selected for a given night with no
further filter changes attempted unless absolutely necessary.  The
SALTICAM shutter is similarly unreliable and may fail completely at
any time.  The SALTICAM software is being updated to provide an
acquisition mode where the shutter is left open while exposures are
repeatedly taken.  This may result in streaking of bright sources
across the field during readouts, but this can be largely mitigated by
binning by 4x4 or more.  Being able to leave the shutter open during
acquisition and slit viewing will significantly extend the lifespan of
this and future shutters.  Lastly, some oil or other contaminant has
worked its way into the cryo-cooler system which prevents SALTICAM
from reaching its nominal operating temperature.  The temperature it
does manage to reach seems to vary with time and is often warm enough
that the thermal noise seriously impacts our ability to acquire faint
targets.

A decision has been made to move forward with plans to completely
re-plumb the SALTICAM cooling system and replace the coolant.
However, there may be significant lead time required to source the
necessary parts and materials.  In the meantime work is ongoing to
port some of SALTICAM's acquisition capabilities to the RSS camera
control software.  The most important bit is the ability to select
guide stars to position the RSS guide probe.  Work is also ongoing to
prepare our spare acquisition camera, called BCAM, so that it's ready
to go should SALTICAM fail completely.  SALTICAM will have to be
removed to perform the re-plumbing so BCAM will be needed to fill in
then as well.  It is hoped that fixes to the shutter and filter
mechanisms can be effected at the same time as the re-plumbing.

=======================
Semester 2012-2 Summary
=======================

A summary of the results of the recent proposal deadline have been
posted on the SALT Astronomy blog:
http://saltastro.blogspot.com/2012/08/2012-2-proposal-statistics.html

102 proposals were submitted with an average oversubscription rate of
1.9, but a full break down of the proposals are given on the blog
post.


=======================
Science WIKI
=======================

To provide a common area for the SALT community to share information
about SALT data and SALT science, we have set up the SALT science
wiki: https://sciencewiki.salt.ac.za/index.php/SALT_Wiki.

The science wiki is accessible with your WebManager login.  Please
feel free to contribute information to the Wiki and share your
experience with SALT.

=======================
SALT Sandbox
=======================

To support and provide a place for the addition of new tools and
scripts related to the processing of SALT data, we have started the
SALTSandbox repository on github:
https://github.com/saltastro/SALTsandbox.

In particular, this repository provides a place to share code that
others might find useful, but might not have a place yet in the PySALT
package.  So if you have developed some code that might be useful to
others, please fork the code and contribute to it!

=======================
PySALT Update
=======================

A new version of the PySALT software has been released.  There are no
major changes in this version, but it does include some critical bug
fixes required for the performance of different packages. New versions
of the software can be downloaded from http://pysalt.salt.ac.za/


=======================
PIPT Update
=======================

New versions have been released for the Salticam and RSS Simulator as
well as for the PIPT.

The new Simulator versions let you select the filter (U, B, V, R or I)
to use for normalizing a generated spectrum. In case of a
user-supplied spectrum you may choose whether to supply actual flux
values or to normalize the spectrum with one of the above filters. In
addition, you may save and load simulation setups.

When using the new version of the PIPT, you may attach saved
simulation setups to a phase 1 proposal. This not only facilitates
checking your proposal, but also allows you to reuse the setup in a
subsequent phase 2 proposal. The new PIPT version also lets you add
information about the status of previous proposals and to flag a
proposal as a priority 4 one.

While you may still submit proposals with the existing PIPT, you are
strongly encouraged to update your software and make use of the new
features.

Links to the new versions can be found at:

2012-2 Proposal Statistics

For the second semester of 2012, 102 proposals were submitted from the SALT partners for observations.    The first one submitted was by Daniel Holdsworth of Keele University and the last one submitted was by Mickael Coriat of University of Cape Town.  A total of 1413 hours were requested from 739 hours available to observe almost 900 different targets.   12% of the proposal request SALTICAM observations and 95% of the proposal request some RSS observations.    Over 78 different principle investigators submitted proposals with 260 co-investigators from 83 different institutions, including 8 different South African institutes.  

In these proposals, a wide range of different objects are targeted including  538 different galaxies, 244 stars, 60 planetary nebula, 8 clusters of galaxies, and 30 objects of unknown nature.

The proposals are currently under technical review by the SALT staff.   They will then move to the
telescope allocation committees at each partner for scientific review.   The allocations of times
should be announced around the 1st of October with the semester beginning on the 1st of Novemeber.
