Pre-Session Weather Forecast (API data from darksky.net)
Pre-Session Weather forecast showed overcast conditions (cloud cover 100%) with possibility of light rain showers in first part of night, giving way to clear stars from 02:00 onwards (cloud cover 25-39%) with very low probability of light showers.
Temperatures 5°C falling to 3°C by dawn.. Moderate Wind (13-16 mph)

Observatory was set in AutoStart mode, so that session would begin would automatically commence when
sky conditions became suitable for observing.   In the event skies were overcast until 01:00 (with rain at 00:45) and
then remained clear until dawn except for a passing cloud with spots of rain at 02:55
Temperature of 4°C at 01:00 fell to 1°C by dawn. Winds light to moderate.
