Session Aims & Highlights (2019-11-07)

Main aims

  1. Smarter Suspension:  Test bug fixes to new code that suspends session if 'AllSkyStars' count falls below 20
  2. Targets: Acquire images of a selection of new targets plus monitoring of previous variable stars, nearby stars and comets.
    (Rain and/or cloud was expected to interrupt or possibly end the session at some point)

Pre-Session Weather Forecast (API data from darksky.net)
Forecast showed some initial clear patches, but with cloud progressively developing through the night, but otherwise dry and calm
In the event there was a moderately clear interval between 18:30 and 22:30, with another clear interval at 02:30-03:45. 
Transparency wasn't great at any stage.
Operations didn't start till suspended at 21:50 and took advantage of clear intervals, suspending when sky deteriorated.
