              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had rain shortly before sunset and heavy clouds at the start of the night.  I opened for a while but the cloud got thick again, and then I closed in a hurry when there seemed to be raindrops on the cloudcam, but those turned out to be a false alarm.  Later re-opened and the sky improved considerably for first half.
The red side contamination posed a serious problem for the second observer's science, but other observers are able to work with it depending on their science.
