Report for night 2010-06-15

SA: Amanda
SO: Freddie
Others: Charl, Ockert, + other day crew and IQ people
========================================================

TESTING. Telescope commissioning.

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

* Took 7 tracks to their ends, in various position and
directions (explicitly had tracks ending in lower left & right,
upper left and right). No major problems.

* Moved dome to a variety of positions, but could not
replicate the dome-following error.

Report for night 2010-06-14

SA: Amanda
SO: Freddie
Others: Charl
========================================================

TESTING. Telescope commissioning.

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

* Got telescope/tracker up and running by pointing N and
taking a short track (aborted).

* Took an extremely long S. track, ~10400 seconds. No problems,
ended 10 sec. before timeline said it should.
Took a shorter N. track -- ended early with 2 hexapods being
full (although that wasn't clear from the display, which was doing
weird things).

* Hitesh notes that initial mirror alignment can be completed
as soon as they get a good night to open. After that alignment,
we can do CCAS/MACS tests.

Report for night 2010-06-10

========================================================

----------------------------
Notes and messages
----------------------------

Summary:

1. Continue to test tracker and
tracker+structure+dome (but without shutter).

No any major problems were detected.

2. 11 pointings to the random objects were done with
calculation of time for each. See log for details.

3. ELS display fixed.

Welcome to the SALT Astronomy Blog!

By popular demand, we have launched this blog as a public interface to what's going on at SALT. It will initially be devoted to posts about the progress of SALT's recommissioning. Eventually it is expected to become a general SALT blog with occasional posts about specific items or events and regular automated posts generated by the SALT Astronomer logging system.

Summary Night Report 20100609

Report for night 2010-06-09

SA: Alexei
SO: Patrick
Others: Sharl, Janus, Anthony
========================================================

----------------------------
Notes and messages
----------------------------

Summary:

1. Tracker was tested as the first step
and tracker+structure+dome (but without shutter) after that.

No any major problems were detected.

2. Tracker moves in X,Y directions were tested first and
normal observation mode after that, where objects for pointing were
selected using OPTI, sent to TCS and telescope started after that.

No any major problems were detected.

Small problem with OPTI was detected (for Encarni):
The last version of OPTI takes into account
proper motions in the different way compare to TCS.
For this reason, objects selected with OPTI were not
accepted by TCS finally.
Please, check.

3. 10 pointings to the random objects were done with
calculation of time for each. See log for details.

4. ELS display does not show RA and DEC.
Needs to be fixed.

Notes and messages
----------------------------

Bit of shutter work during the afternoon.

Summary:

No new issues identified, here is a cumulative issues list
to work on and to keep an eye on during next week -

- Louvres.
- Cable wrap at N structure movements.
- External humidity warning.
- a few temp measures, see log 20106002.

- Dome shutter should be ok, but keep monitoring.


Working ok so far:

- EDS, ELS, CCAS shutter, CCAS fan, AC, FF-fan, dome movement,
structure movement other than extreme N.

Tracker will be tested next week.

========================================================

TESTING. The first "night" of the new SALT season.


----------------------------
Notes and messages
----------------------------

Summary:

Tested ok with first try:

- EDS
- CCAS shutter
- CCAS fan
- dome movement

Tested ok, but not first time:

- false-floor fan (isolator)
- air-conditioning (reboot of BMS)
- ELS (had to restart)

Issues or failures:

- Structure movement:
ok otherwise, but cable wrap problem every time at North.

- Dome shutter:
proximity limit switch appears not working well, could eventually
open/close, but system does not know it's open.

- Louvres:
will open only to 20% in 'automatic'. Deon to check next week.
when in 'manual' all is fine, can open to 100%.

- External humidity warning came on repeatedly for no reason.

- ELS appears fine otherwise, but the Alarm section is empty, still
under construction?? it says "control could not be loaded"

- several isolated wrong temperature measures, see end of log.
