The program is predicting a solar transit of the ISS just after 4:34pm this Friday afternoon, visible from central Bolton:

Ross,
Are those time GMT or BST?
Cheers,

Are those time GMT or BST?

They are BST (="daylight saving time") - I manually set a +1 hour offset in the program over the summer months.

After a mostly cloudy day it did start to clear around 4pm, but at 4:34 there was dense cloud in front of the Sun, whereas just 60-sec later it had cleared enough to get this image:

This is the set-up which I used:

Using the Society's Trust webcam and driven EQ2 mount - only the telescope (and computer) are mine.

This high-tech shade (made from an old cardboard box!) is necessary so that I can see my netbook screen in bright sunlight.

Then the sky got much clearer from 5pm!
