              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
20:52 alt 65 the alt motor stopped.  It didn't throw an error, it just had to be reinitialized, which I did and everything was fine.
The afternoon was very gray and humid but things became borderline enough around 20:30 that I was able to open. The humidity never reached below 80% but we were able to stay open until 02:43.  Seeing was actually pretty good!  Around 1". But, the humidity killed us in the end and when it became foggy around 5:30 so I threw in the towel.
