Pre-Session Weather Forecast (API data from darksky.net)
Pre-Session Weather forecast showed a clear spell in middle of evening (cloud cover 0-23%) but clouding at 22:00 to 02:00 (cloud cover 54-78%) ,
becoming totally overcast from 02:00 onwards.  Minimum temperature 6 degC.
Wind becoming strong onwards dawn with potential rain (heavy rain forecast from 08:00 onwards)

In the event there was a clear spell from 18:00 to 20:10 but transparency and seeing were fairly poor, and sky
was bright due to moonlight and cloud reflection. Cloud thickened at 21:45 and session suspended.  
User intervention made to finish session at 23:30 due to  cloud and rain risk.
