              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started overcast with high winds and passing rain.  Many storms persisted in the area.  Around 22:00 it started to clear, but radar showed several storms narrowly missing us. We were able to open for second half to partly cloudy skies. Seeing was good, but guiding was plagued by having to dodge clouds. We were guiding in manual mode, and Russet logged in and worked some magic to allow guiding sans flatfield, which made it easier to guide on the dim target.  We observed until it was too bright to continue.
