              ------------- ACTIVITY LOG --------------
Observing Specialist: H.Abbot

gcam was fine during afternoon checkout, but received error message 'gcam f text="\"\""' when trying to expose on NA2 guider in the night. Subsequent exposures returned 'gcam f text="guider is running a previous command."' Restarted nubs and it worked again. Happened twice. 

Beatuifully clear night with a humidity spike at 1900 which cleared quickly. No telescope issues to report.
