Support: Steph Snedden



---=== OBSERVING PLAN ===---

Monthly checkout


---=== OBSERVING SUMMARY ===---

PT FF lamp was replaced, and normal sequences of bias and flats were taken
and compared with frames took before summer shutdown.

A sequence of imager doghouse bais were taken and examined, they are normal.

A few spectro bias were taken. examination shows that the bias level of b1 is
out of spec. 

guiding camera communication was checked.

Mirroes were home/relaxed.

weather conditions and left engineering work prevent me from doing other 
monthly checkout tasks.


Problems: (1) Watcher gives the critical error: exec_boot.
          (2) SP2 shutter sensors are off.
          (3) CCD 4 temperature is out of its nominal range.
          (4) the bias level of b1 is more than 10 time higher than its
              normal value. 
          (5) the display of instrument lift can NOT be turned off.




---=== OBSERVING LOG ===---

Setting up:

   When I started a watcher session from MONX 3 this afternoon, an error 
message of cannot read errorFlags came out while the session was successfully 
launched. However, everything was fine when I started another watcher session 
from host2. 

PT:

FF lamp was replaced, normal sequences of bias and dome flats were taken, 
and compared with corresponding sequences taken before summer shutdown.
weather prevent me performing other checkouts.

Imager monthly checkout:

  When the first goDrift -bias was issued, it returned with an error of voltage
amplifier setting improperly. "iack" and "setImagerAmpsOn" solved the problem.
A doghouse bias run was taken (run # 6246), Frames look normal on displays. A
few frames were checked with saodisplay and they are normal. Lighting 
threatening prevents me from flat check.

Spectro monthly checkout:

  The engineer team is still working on the communication between arc lamps and
SOP session. This limited my checkout tasks.

  Watcher gives a critical error: exec_boot, an iack command was issued. It did
not solve the problem.

  Watcher complaints about sp2 shutter off, mechSend s for sp2 returned both 
shutter_open_sensor and shutter_closed_sensor are off.

  Watcher also complaints on ccdtemp on CCD4. I monitored the temperature from
this afternoon with "cc # tcheck", and found CCD 4 temperature is increasing: 
from -84 (at 4:30PM) to -82 (9:00PM). French knows this. 

   A few spectro bias were taken, and checked with saodisplay. It turned out 
that bias frames of b2, r1, and r2 are normal. But the bias level of b1 is 
about 17900, 15 times higher than its normal values. 

  Guiding camera communication was checked with gcam, and it works properly.

  Mirrors are home/relaxed.
