Hi Niko
We Melbournites haven't been having much luck with the comet.....
The cloud may be back for tonight as well, too.
We're heading to Sydney to visit rello's and plan to leave Melb. around midnight/1AM and hope to setup somewhere on one of the roadside stops on the Hume - as long as the East/SE is not blocked by the Dividing Range, we should be ok. I remember when Halleys was here I'd stopped somewhere just before Seymour, and the sky was nice and dark - though there were hills to the East.
Maybe head down south, Berwick way?? Think you'd be past the hills then, and Melbourne's glow would be behind you.
Gee, I'm envious of those who've seen/photographed it....
Good luck
John D
