Thanks, David. That's very helpful.
Yeah...Astrocalc is great. I've been using it for ages and find it very reliable for moon and GRS transits...far more reliable than my version of SN Enthusiast.
Although I'd check your times, there. I just checked tomorrow's calendar advisory for GRS and Ganymede and it'll be 2am for us here in Bris. By 3am, the GRS has just about rounded the limb.
I would have thought there'd be no 'timing' probs now that we're all on EST (non daylight saving time)?
Cheers.
