              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
We had some thin cirrus clouds at sunset, but it cleared up and we had a nice clear calm night.
Apollo hit 6 reflectors!
We spent the first part of B-half taking cals.
I stopped an echelle exposure and it got stuck "integrating". I restarted the echelle and echelleExpose nubs and then hit the Abort button which let me take another exposure, everything seemed fine after that. No other telescope or instrument problems.
