Allan Rahill and Attilla Danko (Accurate Weather Forecasting for Astronomers, Atmospheric Seeing: How You Can Help Create An Accurate Forecast). Allan Rahill has been a professional meteorologist for 22 years, serving all over Canada, and an amateur astronomer since the Apollo program. Attilla Danko has been a software designer since punched cards, and an amateur astronomer since Newtonian pipe-mounts. Both think that seeing a 15th magnitude puff of gas inside a globular cluster is tons of fun. Allan and Attilla will conduct two presentations on weather related topics that will help you plan your next observing session.

Accurate Weather Forecasting for Astronomers. Astronomy reveals the splendors of the universe. But we can't revel in cosmic wonder when it's cloudy. Mundane weather forecasts are not accurate enough for planning an observing session. Allan Rahill will show another perspective of the weather service and explain how it is possible to produce the most accurate forecast for astronomers. Attilla Danko explains how to predict clear skies, without knowing any meteorology, using the Clear Sky Clock interface to Allan's forecasts.

Atmospheric Seeing: How You Can Help Create An Accurate Forecast Under good seeing, a look at Jupiter reveals an endless visual feast. Under bad seeing, nearly nothing is seen and much energy is expended making the excuse "There is nothing you can do about seeing." Common wisdom is wrong. Allan Rahill explains the physics behind atmospheric seeing and his several years of research to create a numerical seeing model. Attilla Danko explains how observers all over North America can report observations of seeing conditions to help Allan refine his model into the first accurate seeing weather forecast.
