1. By zooming out in the 3D view port, satellites, stars and planets appear in their orbits [3] around the Sun. - Forecasts based on predicted Kp index estimated by the Space Weather Prediction Centre (NOAA-SWPC). - 3-day space weather condition forecast as news ticker. - Two-Line Element (TLE) satellite orbit calculations [9]. - Sun and Moon daily elevation plots with rise and set time. - Target web links added to satellites, stars, planets and position. - All-sky camera links to the Boreal Aurora Camera Constellation (BACC). 1] Sigernes F. , M.

10. The Aurora Forecast 3D is a tool to track down where the aurora is located in the sky from any location on planet.
11. The short term forecasts are up to +6 hours, while the long term forecasts are up to 3 days ahead in time.
1. No error message is shown so I cannot provide more details.I like the display - but the app seems determined that there is no Internet connection (there is, and all other apps are working) and is unable to update...5stars; Very thorough; take some time to explore its many features.
2. A nice option would be to set up an alert when a storm is forecast (or is that function already there and I missed it?)Used to work great but now it crashes when I open it.
3. I look forward to seeing if the aurora visibility indication is accurate! Cool app.Amazing and very informative This app is very easy to use, especially for answering the question, "could I have seen the aurora last night?".
4. Even has a star chart feature, and let's the user move backward and forward in time about a day.Great app, though a lot of options/functions to figure out.
5. The help feature and video are pretty good, but might need to be updated for the current version.
6. After posting that info, there was an update which fixed the crashing problem.
7. This app was and will be my go to app for Aurora.Love(d) the app, but after upgrading to Android 12, the app continually crashes 1 second after opening.
8. This app is visually very appealing, has some great features, and is pretty easy to use once you get used to it.
9. I like the astro background explanation in the info section for people who want to learn more.
10. I see a few other things on the globe display, but don't see an explanation of what they are (yellow map pin?).
11. Update 1/5/21 I did install the new version and it is working wonderfully.
