Want a quick way to check for dark clear skies in the Breezy Point Observatory area? A clear dark sky chart has been added to the KVAS website. Go to kvaswv.org and scroll down to the bottom left of the page and see the sky predictions.
What is it?
Created by the late Attilla Danko and maintained for now by his widow at CSCCharts, it's the astronomers forecast. It shows at a glance when, in the next 96 hours, we might expect clear and dark skies for one specific observing site. It's is specifically intended for amateur astronomers. The data comes from a forecast model developed by Allan Rahill of the Canadian Meteorological Center.
Read from left to right. Locate a column of blue blocks. That's when the sky will likely to be clear and dark. The darker the blue the better for observing. The clear sky chart predicts hourly cloud cover, atmospheric transparency and seeing. (Good "seeing" occurs when the air is steady enough to allow you to see fine detail on planets through a telescope.) That means you can plan whether to observe galaxies or planets or stay home and process image data.
Charts are available for many sites in the US and Canada. Check out:
