Ganymede Occulting Io - Animation!

Postby mike salway » Tue May 26, 2009 8:56 pm

This morning I was able to capture my first Galilean Moon occultation, when Ganymede passed in front of Io, covering about 40% of the volanic moon.

The seeing was reasonably stable, maybe 6.5/10 and the morning started off beautiful and clear. Some cloud bands came through right at the wrong time, ruining some of the sequences right in the middle of the occultation. Of course it cleared completely after the event was all over.

Despite the annoying clouds almost ruining my chances of capturing anything of the occultation, I was able to image enough of the event to put together this 32-frame animation, covering 33 minutes of elapsed time. Detail and albedo features can be seen on both moons.

For more info about my capture and processing settings for this event, and why it’s even so special at all:

Thanks for looking.

Absolutely spell-binding!

And there are people who see no merit in occultations and eclipses?
Newton would have given his right leg to see this.

Thanks for your feedback guys, much appreciated.

Here's a colour image from a little bit before the occultation:
