Weather conditions are very important for astronomy, well... for lots of things really.  Too many clouds interfere with visual observing.  Too much wind interferes with astrophotography.  Too cold makes everything miserable.  A too bright Moon hides almost everything else.  So it really helps to know what's going on with the weather.

On a typical night around 1500 sky photos are taken by the Oculus Allsky camera. Those images are then combined into this video so cloud motion can be observed. Watching the Milky Way pass overhead is pretty cool too!

Chart of current weather data

The chart above shows the weather conditions at the observatory for the last 24 hours. Newest data is on the right, oldest on the left. It also shows the "HtrPwr", which can range from 0% to 100% of available power to be applied to the Allsky Camera's heater. The goal is to only apply enough heat to keep the camera's dome from dewing up. Additional heat beyond that amount would needlessly degrade the image quality.
