              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
Needed to adjust the tilts of both R300 and B400 gratings at checkout.
Both JH04 and UW05 reported not recieving their setup email from 35m-observing.
I did not recieve an email response from WY02,
Surprisingly, the clouds dissipated enough that we could open around 21:45.
JH04 had acquired all the data they could under the partly-cloudy conditions and handed over the rest of their time (about 0.5 hr) to UW05 at 00:41. That time is marked as OBS for JH04 and UW05's time is marked as starting at their scheduled time.
UW05's targets were too faint to observe with the cloud cover, so they called it a night at 04:30.
