                ------------- ACTIVITY LOG --------------
 Observing Specialist: G.Saurage
First half tonight APO hosted an open house. We had several tour groups come through
and look at the telescope and instruments. Unfortunately the weather would not allow
us to open for on-sky observations with the eyepiece, except for the very first
group before sunset, but all the tours seemed to enjoy their visit all the same.
High winds, thick clouds and a little rain and snow...
Second half rotator needed to be reset as per instructions form Fritz. First attempt
didn't take, but Fritz logged in and was able to get it to reset.
Agile left mounted for daytime calibrations.
