Just to get us in practice for the Venus transit at the start of next month, there should be two transits of the ISS across the solar disk tomorrow afternoon (3-May). This map shows the regions of visiblility:

The blue lines show from where the Space Station will pass across the Sun's equator, and the red lines show the limits of transit visibility.

The first event is at 14:45:45, viewable along the line running from Tottington to Standish.

And on the very next orbit at 16:21:29, those along the line from Middleton to Parbold (including me!) should get their chance.

But please take great care when observing solar events - don't blind yourself or melt your CCD!

Well, the forecast rain didn't arrive, but the cloud did. :(
By 4:15 it was thick enough to mask the large sunspot which I had seen clearly in the morning, so I had no chance of catching a fleeting glimpse of the ISS transit.

But I did manage to catch another transit of sorts:

One of the frames of my video shows part of an aircraft wing and jet-engine, just before its contrail sweeps across the Sun.
My original video was 1.5 minutes of 640x480 AVI, but I've converted this 15-second clip into very compact little MPEG movie.

Well done Ross. I am sure it is scant consolation to capturing the ISS transit.
Still well done!

Ian
