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

        Monthly Spectro checkout





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



Completed all required monthly checks, vis., bias, dark, flat, and arc.  Both 
spectrographs are now focused and collimated. 

As described in the monthly checklist, the 98th percentile reported by 
Son-of-Spectro should be less than 15 ADU for dark frames.  The reported ADUs 
for this month were slightly higher.

I noticed that the spectrograph pressure, which should be about 28, was down 
to 24.

---=== TELESCOPE STATUS ===---


07:30Z I moved the scope to 121,30, 0.  I also connected the spectrograph's 
LN2 and pushed in the west and north e-stop buttons. The lower enclosure was 
shutdown, and the recirc fan in the upper enclosure was turned on.
