If you go to http://www.caasastro.org/, you will find the "Clear Sky Chart" on the home page.
The chart is a time line for weather. If you click on the chart, you will link to a detailed
explanation. You will also find links to other charts. Pick the closest one to you for local weather
conditions. For example, let's use the NHAS chart: The first 4 bars are the most important: Is it
cloudy? How clear is the sky? What is the "Seeing", and finally, how dark is it? The deeper blue
the squares are, the better. In the chart below, Saturday night looks very good, while Sunday night
will be cloudy.
