Clear Sky Chart
The Clear Sky Chart is developed by Attilla Danko using data from Allan Rahill at the Canadian Meteorological Center (basis for the Clear Sky Alarm Clock). It shows at a glance when, in the next 96 hours, we might expect clear and dark skies for one specific observing site. It is specifically intended for amateur astronomers.
An Apple app is also available.
