Which satellites are included in the flyby report?
The most interesting ones! The team of experts at spaceweather.com monitor current launch events and objects in Earth orbit to report the brightest, coolest, and most newsworthy flybys. We sort through tens of thousands of Earth orbiting satellites so you don't have to.

How can I find out which satellites are currently being tracked?
All of the satellites and objects currently being tracked are listed in the "About" section of the app. The satellite set is updated as conditions in the night sky change.

Sometimes I don't have any flybys in my report. What gives?
No satellites are flying directly over your location for a few days. This happens on rare occasions, and it is temporary. Wait a few days.

If I enter a latitude and longitude that are far away, the flybys are off. How can I fix that?
In "Worldwide" mode the app uses the internal timezone to calculate flybys. If you set the latitude and longitude for a far-away location, you need to also adjust the timezone accordingly in your general settings.

Why don't I ever see the Hubble Space Telescope?
You might not live in the right place. Some satellites are visible only from low latitudes due to their orbits. The HST is one of these.

Why didn't the app show a satellite flyby for my location that another website listed?
Because we're smarter than they are. Our flyby prediction software uses a minimum angle of transit elevation to make sure the flyby is far enough above the horizon to be easily visible. This minimizes the risk of going out and not seeing anything.

Does the app show flybys when I am not connected to the internet?
Yes. Once the flyby schedule is downloaded, it remains on your phone and you don't have to be on the internet to use it. However, you do have to be on the internet to download the flybys initially and to update your schedule as time goes by.

Do I have to input my location every time I use the app?
No. Once you've input your location, the app stores it for future updates. Or, if you use GPS mode, the app will automatically know your location.

When does the app update the flybys?
Every few days and/or when you enter a new location and/or when the satellites change. In other words, almost constantly. The flybys schedule is never out of date. Caveat: You have to be connected to the internet to get flyby updates.

What if a new satellite shows up?
The app will update itself when new satellites are added.

Why are magnitudes brighter for lower numbers?
That's Astronomy for ya!
