              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had heavy clouds and nearby rain all night, with a few drops of actual rain and some high winds for variety.
I had to restart the DIS blue ion pump twice.  It did not send email about its problems either time.
