              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
My observer started a 1800s exposure with KOSMOS and was unable to abort it.  It ghosted the stop & abort buttons.  I tried the abort and it did the same.  I followed the wiki and needed to restart the ICC to fix the issue.  Luckily I did not have to restart the torrent.
Clouds formed over us around 03:15, we got back on the sky at 04:15.
No telescope problems tonight.
Elevated dust levels, max around 4300cts.
