Satellite crossing the Moon?

[kerrylewis]

I was setting the scope up yesterday in daylight (just after 1800) and using the moon to align. To my amazement I saw what looked like a satellite crossing the disc. It was the right sort of speed and I'm sure it wasn't a plane - there was no evidence of a plane shape and I thought I saw a satellite sort of shape with solar panels. It was over in seconds and I didn't note the exact time. I was pretty sure  it must have been the ISS but on checking it was not around. On checking Sky Safari a likely candidate seems to be  a Globalstar satellite but not sure how big this would look( the moon was about 80% of the FOV). The time is about right (1810) and the speed looks right; it doesn't quite cross the disc but is a close graze. That could be a location error perhaps or just inaccuracies in the data?

Whatever it was it was an exciting and unexpected thing to see and I've never seen anything similar.

You might want to use calsky for more exact data. Your location has to be spot on, as transits like that are often only visible in a small corridor. You'll probably find the right candidate if you search within the correct time frame.

moon and sun transits also have a seperate piece of the website, it might be handier to look it up there.
