              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend&R.McMillan
We’ve had high 0.3-micron counts, likely due to smoke from far away as we also had a nice neon pink sunset.
The clouds were really bad tonight!
Clouds and virga on the radar at sunset. Opened a little after 22:00 when the radar cleared, closed up again close to midnight when the radar came back. It cleared up (radar and clouds) for a little bit after changeover, but after 03:20 we weren't able to get anything through the clouds. We gave up at 04:35.
Enclosure Optidew dewpoint sensor is behaving erratically, but Dataq still ticking away at 05:11.
Happy summer solstice!
