---=== OBSERVING TEAM ===---
Night: Steph Snedden, Shannon Watters
Swing: Kaike Pan
---=== OBSERVING PLAN ===---
        Science!
---=== OBSERVING SUMMARY ===---
It was cloudy off and on throughout the night (of course there wasn't any
precipitation).  We acquired signal on 2 plates.
---=== OBSERVING LOG ===---
Afternoon:
-----------
All systems were checked, and working properly. The spectro focus was set for
6.5 C.
Data for mjds 54590-594 were removed.
