              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started out with clouds and rain nearby on the radar, so we did not open at dusk. It cleared enough by 22:00 to open.  Ecam was showing shutter issues, but no vertical lines.
It was hazy, but seeing was good. The haze grew thicker through the night, but GS03 had bright targets and we able to observe until twilight.
Telescope was left parked at 104,83 for apollo servicing.
