With thanks bigjoe.
Thanks Joe,
I can't take too much credit, just was looking it up for myself in Starry Night and decided to export the animation & put it online to share. Took a few goes before I got the size and speed correct. Figured nobody wants to watch it in real time on the screen (5hrs)

This evening, I just made a bigger screen filling animation. Follow the link to animation 2 - file size 19MB.

Note that in Eastern Australia, it is Sunday morning (ie Saturday night) so for once we don't have to go to work bleary eyed to watch something interesting.

The European Model http://yr.no is even saying clear Saturday night in this region. Euro model works well for this region. Skippysky (GFS) also indicating clear. Cloud free night is offline at time of writing 6:30pm Thursday 1/3.

Anybody intending to observe, the times published last night are only approximate taken by observing the contacts in Starry Night.

Tonight, I have updated the site with the times below, taken from -
