About
Astrospheric is the premier weather forecasting service designed specifically for the astronomy community, including amateur stargazers, professional astronomers, astrophotographers, and university observatories. Unlike generic weather apps, Astrospheric generates hourly, location-specific forecasts tailored to the unique needs of night-sky observation. At the core of Astrospheric is its exclusive integration with Allan Rahill's atmospheric seeing model — the only service to provide hourly seeing forecasts from this widely respected scientific tool. Its transparency forecast uniquely incorporates wildfire smoke data, helping observers avoid hazy skies caused by regional fires. The platform draws on multiple forecast models (RDPS, GFS, ICON, NAM, NBM) and offers a multi-model cloud ensemble through Astrospheric Pro, so users can gauge forecast confidence at a glance. Additional features include an Astronomical Clock, moon phase and altitude tracking, Aurora nowcasts, wind and dew point layers, satellite imagery, and a light pollution overlay. The Subspace community feature lets members of astronomy clubs connect, share images, plan events, and coordinate observing sessions. Available as a responsive web app and native iOS/Android apps, Astrospheric also exposes an API for developers and embed tools for astronomical societies. It is the go-to planning tool for anyone who needs reliable, astronomy-optimized sky conditions before heading out under the stars.
Key Features
- Allan Rahill Seeing Forecasts: The only service providing exclusive hourly atmospheric seeing forecasts powered by Allan Rahill's scientifically respected seeing model.
- Wildfire Smoke Transparency: Uniquely integrates wildfire smoke data into its transparency forecast so observers can anticipate and avoid smoke-degraded skies.
- Multi-Model Cloud Ensemble (Pro): Astrospheric Pro aggregates multiple forecast models (RDPS, GFS, ICON, NAM, NBM) into a cloud ensemble, giving users confidence levels for clear-sky predictions.
- Astronomical Clock & Moon Tracking: Provides a real-time Astronomical Clock alongside detailed moon phase, altitude, illumination, and upcoming lunar event data for precise session planning.
- Subspace Community: A built-in social platform for astronomy clubs and societies to connect, share astrophotos, plan events, and coordinate group observing sessions.
Use Cases
- Astrophotographers planning multi-hour imaging sessions by checking seeing and transparency forecasts before heading to a dark site.
- Amateur astronomers identifying cloud-free windows for visual observing of planets, deep-sky objects, or meteor showers.
- Astronomy clubs and societies using Subspace to coordinate group star parties and share post-session images.
- University observatories and professional astronomers scheduling telescope time based on reliable, model-backed sky condition forecasts.
- Observers in wildfire-prone regions using the smoke-integrated transparency forecast to avoid smoke-degraded nights.
Pros
- Astronomy-Specific Accuracy: Forecasts are tuned specifically for sky-quality metrics like seeing and transparency that generic weather apps completely ignore.
- Exclusive Smoke Integration: Wildfire smoke incorporated into transparency forecasts is a unique and critical feature for observers in fire-prone regions.
- Multi-Platform Access: Available on web, iOS, and Android with a consistent experience, plus an API for developers and embed tools for societies.
- Active Scientific Partnerships: Continuously integrates new weather models and collaborates with leading scientists to improve forecast quality over time.
Cons
- North America Only: Forecast coverage is currently limited to North America, making it unavailable for astronomers in Europe, Asia, or the Southern Hemisphere.
- Best Features Behind Paywall: The multi-model ensemble, unlimited favorites, and weather alerts require an Astrospheric Pro subscription.
- Niche Audience: The tool is highly specialized for astronomy use cases and offers little value to users outside the stargazing community.
Frequently Asked Questions
What makes Astrospheric different from a regular weather app?
Astrospheric forecasts sky-quality metrics that matter to astronomers — atmospheric seeing (image steadiness), transparency (sky clarity including wildfire smoke), and cloud cover — using models specifically designed for astronomical observing, rather than general precipitation or temperature forecasts.
Is Astrospheric free to use?
Yes, Astrospheric offers a free tier with core forecasts. Astrospheric Pro is a paid subscription that unlocks the multi-model cloud ensemble, unlimited favorite locations, weather alerts, and other advanced features.
What is the 'seeing' forecast?
Atmospheric seeing refers to the steadiness of the air above you — poor seeing causes stars to twinkle and blurs fine planetary detail. Astrospheric provides hourly seeing forecasts sourced exclusively from Allan Rahill's scientifically validated seeing model.
What is Subspace?
Subspace is Astrospheric's built-in community feature for astronomy clubs and societies. Members can create or join groups, share astrophotos, plan events, and coordinate observing sessions with others in their club.
Does Astrospheric have a mobile app?
Yes, Astrospheric is available as native apps for both iOS and Android in addition to the full-featured web application.
