Weather statistics

The cumulative monthly weather statistics presented below are created using the measurements of a Davis Vantage Pro2 Weather Station installed on a pole 5m above ground just 30m from the 1.2m telescope, which is at an altitude of 900m above sea level. The night duration is defined as 1hr past sunset to 1hr before sunrise. Suitable weather conditions for observations are defined by relative humidity levels below 80% and windspeed below 15 m/s.
