              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Varying clouds all night long, but everybody was able to shoot through at least some of the time.  We even managed to see a couple of targets with the eyepiece!  I counted some time as unusable when we weren't even trying to take on-sky data.
