Some amateur astronomers can't live without their Clear Sky Chart, the handy graphic that forecasts such need-to-know atmospheric conditions like cloud cover, transparency, and humidity. The major problem with Attilla Danko's fabulous service is that it's only available for North America — most of it, anyway.

We received word this morning that now the rest of the world can benefit from a similar website built by Chinese programmer Ye Quanzhi. His Astroweather Panel covers everywhere Clear Sky Chart does not. Select a location by entering your geographic coordinates, or navigate through the place names, organized by country, already in the system.
