Last night while imaging Jupiter, I thought I'd just check which moon was in which position, cause Io and Europa were close together. I thought I'd fire up Jupiter 2 because I haven't really used it in anger but quite a few people swear by it.
The moon positions given by Jupiter 2 didn't match what was in the sky
. Hmmm, so I dragged out my copy of Astronomy 2006. The graphs on there matched the positions I observed - Io and Europa close together on the eastern side. Jupiter 2 showed Io and Europa on opposite sides?
I made sure Jupiter 2 was in real time mode, and time on my lappy was synchronised less then an hour before the observation and hadn't been turned off since...
Anyone else noticed a similar problem wih Jupiter 2?
If I'm doing something wrong, can you tell me what it is?
