ISS Solar Transit and a BIG sunspot in Ha


Recommended Posts

Hi all. There was a transit of the International Space Station across the sun this afternoon at my location (16:02:48 BST to be precise), only a couple of weeks after a transit of the moon here. Only just, though (just over a second!), as it skimmed below the current monster sunspot group AR2192. You can just make it out.

Coronado PST, QHY5 cam @ c. 40 fps.

Well done.  Nicely caught.  If you'd been at the other end of the garden it looks as though it wouldn't have been a transit at all :D

Cheers folks.

Out of interest, the centre line of the transit was 6.89km away, and the width of the path of visibility of the transit was 17.1 km. A bit of maths tells me that my garden would have to be 1.66km long to have missed it completely. I wish! Or maybe my maths is rubbish (but I do have an A-level in it!)

All thanks to http://www.calsky.com/
