RIP iridium flares

I’m afraid it’s not the app, my friends. I just tried another (fortunately for cheap) before realising that a second generation of satellites have been launched over the last couple of years and they don’t reflect sunlight in the same way. It’s almost like a natural stellar phenomenon has been taken away from us. 😢

Always accurate, just wish I lived away from the city to use it more often. The only thing that could improve it would be an automatic alarm.

Really Useful

I guess this is quite basic in what it does - no fancy animations etc - but what it does it’s excels at.

It’s my first port of call to find out what time I can expect to see visible satellites from my locality
