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

        Science!

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

Flat field petal motor continues to run on. The 6:00 petal failed to open on 
one exposure. This needs repair on a Sunday, I'm afraid.

We took several exposures on two SEGUE plates, but neither are done yet. 

Humidity got us toward the end of the night.

Afternoon:
----------
Afternoon checkout had a few glitches. We lost cloud camera communications at 
the end of last night, and when we tried to restart today, we got no images 
transferred. We guess the problem started with the Apache server. Today, the 
weather status was down for a while as well, but apparently came back on its 
own. However, the cloud camera was still down. Here is the process info:

IRSC is running. Or should be.
     
     started at Sun Sep  7 02:38:48 2008
     
Last few images were:
Processes are:
       PID  PPID USER     S %CPU %MEM     TIME CMD
      7701  7698 irsc     Z  0.0  0.0 00:00:00 [python]

/data/home/irsc/data /home/irsc/var/IRSC_RUNNING

There were processes, but no images. We got hold of Jon on the road, and after 
he reached his destination, he fixed a permissions problem related to 
installation of new drivers. This got the cloud camera going again.

The flat field petal is continuing to run on after the petal is opened. It 
is the one in the 6:00 position when facing the telescope.

Night:
-----

02:51Z Clouds cleared enough to start collecting data on
Cartridge 4, plate 3137 - SEGUE
-------------------------------
Guide stars on goToField. Took four exposures totaling 6900s, fighting clouds 
the whole time. We made progress, but the plate is still not done. 

After Connie looked at the first night's data on this plate, we concluded that 
we should continue to use the SEGUE faint stopping criterion of (S/N)^2 >= 50 
in both red and blue cameras.

05:37Z - Cartridge 1, plate 3131 - SEGUE
----------------------------------------
Needed an FK5, but it was just off the edge of the fiber.

08:19Z - Flat field petal refused to open, ruining one exposure before we 
noticed the Watcher error message. Sure enough, the motor was running on. We 
took the downtime opportunity to fill the spectrographs.

We took four exposures totaling 6000s, but the plate is not yet done.

09:01Z - The skies became photometric. We mounted the imager. The humidity 
went over the closure limit. We unmounted the imager. We closed.

10:45Z endNight rejoiced
