Astroweather

For enthusiasts of the night sky, the Astroweather toolkit is an essential companion for stargazing. This specialized weather forecast service is tailored specifically for astronomical observations, providing detailed insights into the conditions that matter most to astronomers and hobbyists alike.

Astroweather harnesses data from 7timer.org, integrating it with advanced astronomical weather forecasts. This includes not only traditional weather predictions but also specific information such as sunset and sunrise times, as well as moonrise and moonset schedules. By leveraging web-based meteorological forecast products, Astroweather primarily uses data from the NOAA/NCEP-based numeric weather model, known as the Global Forecast System (GFS), ensuring accuracy and reliability in its forecasts.

Originally established in July 2005, 7Timer! was an innovative project supported by the National Astronomical Observatories of China. It underwent significant updates in 2008 and 2011, and is now backed by the Shanghai Astronomical Observatory of the Chinese Academy of Sciences. The tool was initially created to serve the needs of the astronomical community, driven by the founder's passion for stargazing and frustration with unpredictable weather conditions.

Astroweather extends beyond basic weather forecasting to offer a suite of services tailored for the astronomy enthusiast. These services include:

• Astronomical event forecasts, helping users plan for celestial events.
• Light pollution maps and satellite images, aiding in the selection of optimal viewing locations.
• Rise and set times for stars, planets, moons, and satellites, providing comprehensive data for observation planning.
• An astronomy forum, fostering a community for sharing insights, experiences, and tips among fellow stargazers.

By combining precise meteorological data with astronomical information, Astroweather serves as a comprehensive toolkit for anyone looking to enhance their stargazing experience, making it easier to enjoy the wonders of the universe under the best possible conditions.
