Notes (S00037)

This imaging session was of nearly 8 hours duration and ran many under unattended script control.  With ambient temperatures of -5 deg C attended operation of the telescope would just not have been possible.    A number of check visits were made to the observatory  to check progress.   The first visit showed that the telescope's sky position  had become lost due to an inappropriate sync following a SBIG driver: A/D timeout. # 800407DD problem.  The script was restarted and then continued without requiring any form of intervention  for 6 hours 40 minutes, during which scripts took a total of 596 CCD Images as part of the following set of tasks :

Variable Stars 

Variables in Pegasus, Andromeda, Lacerta were imaged using Automated Scripting (see Scripting).  New set of variables in constellations Auriga, Gemini, Cancer, Camelopardalis, Perseus and Taurus were commenced.
