One year out

Okay, we are just about one year out and it is a good time to check the weather in the area where you are planning to view the eclipse. I have added a few new links to the web page for the 2017 Total Solar Eclipse. These links take you to weather and atmosphere pages that will be useful in the days just before the eclipse.

One tool amateur astronomers use frequently is called the Clear Sky Chart. These charts predict the weather for a given observer location (normally an observatory or club dark site).  To use, select a location from the map at that is closest to your planned observing site. When you first click a known point, the duration and name of the location is shown. Next click the name of the location to reveal the details.

In the chart, locate the time near the eclipse time. The squares indicate the conditions and blue is good while white is bad. You can hover over the squares to get more details.

The the predictive tool of the clear sky charts is legendary. Some will tell you it is right almost 100% of the time. Others will say it is a wild guess and has as much accuracy as flipping a coin. As far as I am concerned, it is another way to get more data as the eclipse day approaches!
