              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
Cloudy with lots of showers on radar during the afternoon, along with windy and smoky/dusty conditions. The smoke settled enough that we tried opening at 21:00. However, the clouds forming over us were too thick to see anything, and UV01 didn't get any data. GS01 also did not get any data, and with the forecast only looking increasingly bad, they went to bed around 02:00. I stuck it out hoping the weather would clear, but gave up at 04:15.
