The Clear Sky Clock

What is the Clear Sky Clock?  It's the astronomers forecast. It shows at a glance when, in the next 48 hours, we might expect clear and dark skies for one specific observing site.  It's is specifically intended for amateur astronomers. The forecast data comes from a numerical weather model run by those very cool guys at the Canadian Meteorological Centre.


Based on a numerical weather model, Clear Sky Charts are perhaps the most accurate and the most usable forecasters of astronomical observing conditions for over 1900 observatories and observing sites in North America.


It is the brilliant work of Attilla Danko, an amateur astronomer and programmer.
