Astronomically, the forecast for this evening appears to be the following:
The graphic above shows the possible viewing conditions from Doug Azwell's Observatory in Maryland Heights. This Clear Sky Clock graphically represents conditions of cloud cover, transparency, seeing (steadiness of atmosphere) and darkness of sky in the indicated location. It uses weather data including satellite infrared cloud data, jet stream location and other factors to determine the data that it shows. It is typically quite accurate, but on occasion, some variation can occur in the forcast. The graphic is included for information only.
If there is cloud cover, we will meet in the planetarium instead of the observatory. Signs will be posted starting at the entry door guiding your way to either the planetarium or the observatory.
