Clear Skies Chart

Created by Attilla Danko, Clear Skies Charts work as an astronomers forecast for the area. They show where (during the next 96 hours) you might expect to have clear or dark skies for any particular observing site. While we show two of Dudley at Siena’s most frequently used sites below, you can search a wide variety of locations at www.cleardarksky.com

These charts are specifically intended for amateur astronomers. Data for the forecast models is developed by Allan Rahill of the Canadian Meteorological Center.
