Frequently asked questions (FAQ)

I think I saw a bright satellite which could be the ISS but the prediction wasn't in the Heavens-Above list. What could it be?

This almost certainly was ISS or another very bright satellite. We have a cut-off of -6° sun altitude for our predictions, so that satellite passes are only predicted when the sky is reasonably dark. However, these bright satellites can sometimes be seen when the sun is higher, but this explains why they aren't in the list. On the ISS predictions page, you can also select the "all" radio button to show the times of all passes, even those during daylight, and then compare these times with your observation.
