Your astronomy and weather toolkit for stargazing.
Astroweather delivers accurate weather forecasts specifically for astronomical observation.
It utilizes data from 7timer.org, combining astronomical weather forecasts with sunrise/sunset and moonrise/moonset times.
It provides web-based meteorological forecasts, primarily based on the NOAA/NCEP Global Forecast System (GFS) numerical weather model.
7Timer! was first launched in July 2005 as an experimental project with support from the National Astronomical Observatories of China, undergoing major updates in 2008 and 2011. It is now supported by the Shanghai Astronomical Observatory of the Chinese Academy of Sciences. Originally designed as a weather tool for astronomers, its creator is a long-time stargazer frustrated by unpredictable weather.
Astroweather also provides services including:
- Astronomical event forecasts
- Light pollution maps and satellite imagery
- Rise and set times for stars, planets, the Moon, and satellites
- An active astronomy forum
