• 2230 Ian sets up the dome with Dylan and Jason
• 2240-1230 Fixing detector orientation to “north up” and Ian demonstrated how to put on the detector
• 0100 Ian leaves
• 0128 3C 273 was not viable, too low
• 0130 Clouds rolled in
• 0142 Slewed to Vega to confirm that there was no pointing error, cloud cover making it difficult to see high magnitude targets
• 0150 Skipping TON 599 and 3C273 captures due to the high sky cover, and going down to where AM Her observations begin
• 0230 Slewing to BL Lac as requested by Ian. Will be observing Bl Lac as the main target for the rest of the night. Calibration targets will remain the same

Astropol is implementing a technique to ensure that the detector is “north up” - to decrease the amount of drift that occurs during long exposures. If not “north up”, the RA tracking movements can “leak” into the DEC, and move the target vertically on during captures.
