Weather statistics

Whole statistics from 2020A are provided, year by year, on the following graphs. The blue curve represents the night fraction the dome is open, the black dotted one the night fraction where the dome is closed due to meteo. The numbers on the right represent in blue the fraction of time the dome is open when not in technical time, and in blue the fraction of time of (100%-meteo%), the difference between black and blue representing thus lost time due to technical problems (on the telescope or on the dome) or other issues (guiding problems, wrong coordinates, embedded star…). These 2 successive blue/black fractions correspond respectiveley to A semester, B semester, and the whole civil year.The red area is the CoVID closing, while grey areas represent periods of maintenance of the telescope (technical time).

The statistics for Neo-Narval (starting from 2020A) provides the percentages of time the telescope is ready to observe between real observations on the sky (label « Done »), time lost due to bad weather condition (label « Meteo ») and time lost due to technical problems (label « Technique)
