Astrospheric is weather forecasting for North American astronomers, astrophotographers, and most of all explorers.

Using the amazing astronomy data produced by the Canadian Meteorological Center, Astrospheric produces a highly accurate 48 hour forecast for any location in the United States or Canada.

Overlaying cloud, transparency, seeing, and light pollution data onto a map makes it simple to search through the next two days looking for the nearest break in the weather.
