Nice page, but from Woking the cloud's just thick enough to stop me
seeing anything :-(

How do you know how thick the cloud is going to be? It could well clear
before then.

Oops. It would help if I got the date right ;-)

aka BY Cancri.

It also looks as though it may reappear between the ansae and the disc.
If so, an interesting photo op for those with the skies and the kit.


Best,
Stephen

How would you capture this event on a webcam? I was thinking of having
a go but I would imagine it's going to be tricky to set the levels such
that you pick up the star but don't massively overexpose the planet &
rings. I have managed to take pictures of the moons before but I did
that by manually 'deleting' the planet and popping in a properly
exposed shot taken a few minutes later.

Any tips or suggestions?

Maybe the use of a blue or green filter may help...

Actually the surface brightness of the planet and the brightness of the star
are not too different in this case. It is relatively easy to expose for the
Planet and Titan for example which is a similar magnitude to the star.
