              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started mostly clear.  The mirror cover control box needed a reset during checkout.  Skies cleared entirely by 20:00 and stayed clear.  Seeing was good, and the telescope and instruments behaved themselves.
