              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Tspec was not good, I took 1500 darks.
The night started out humid and with areas of fog.  We were able to open at 18:06 when the humidity dropped to safe levels.  We closed again at 19:45 due to high humidity and fog.  We reopened at 22:30 and stayed open the rest of the night.
