              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started partly cloudy, with increasing clouds.
Ecam was showing shutter issues (horizontal lines off of bright stars)
Skies remained mostly cloudy for the night, but the observers had bright targets. We closed around 03:30 due the threat of rain/snow on the radar. We did not open again.
