              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had medium to thick clouds for most of the night, and also radar signals with varying levels of belivability.  I tried opening during second half when the radar signals were further away, but I'm not sure very many photons were gathered.
