Cloud Free Night

Cloud Free Night is an online weather forecast information service, for the benefit of the Australian and New Zealand astronomy community. It is unique in offering a comparison of the widely available forecasts from the United States GFS global model with higher resolution forecasts from the Australian Bureau of Meteorology ACCESS model. The Cloud Free Night website has also been optimised for mobile devices.

Testimonial

"Wow, what a success. CFN had our forecast spot on (Lumeah meteogram)... We set up eight telescopes not knowing how many people would show up. Kojonup, population about 2400 and in the course of the evening we had about 200 visitors... Two hours of continuous photography ensued... What a thrill to see such enthusiasm from entire families from the entire cross section of the community. A very successful outreach event."
