Weather statistics

The cumulative monthly weather statistics presented below are created using the measurements of a Davis Vantage Pro2 Weather Station installed on pole 5m above ground just 30m from the 1.2m telescope, which is at an altitude of ~850m above sea level. The night duration is calculated from 1hr past sunset to 1hr before sunrise. The weather conditions acceptable for observations are defined assuming a humidity less than 80% and windspeed less than 15 m/s.
