              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We had issues with the NA2 guider taking images today.  During shutter replacement Bill forgot to connect a cable to the camera.
The observer started a 9999 exposure sequence with KOSMOS.  Unfortunately we don't have an easy way currently to abort or stop the exposures.  About 40 mins before the end Russet attempted to stop the exposure sequence but unfortunately it was a bit more complicated and she needed to drive into the site to fix the issue.  Russet quickly got things back in shape once she arrived.
No problems second half.
