ISS planetary transits

[lukebl]

Does anyone know of an online resource to predict transits of the ISS over the planets from any given location? I’d like to have a go at imaging the ISS transiting the disk of Jupiter.

Since the recent demise of the awesome Calsy.com website which had all sorts of useful information, there doesn’t seem to be anything similar out there. There are sites which predict Lunar and Solar transits, but not planetary. Any suggestions?

Here’s an example by a chap called Arthur Franke. I hope he doesn’t mind me using his image

Is this any good?

Its an app you have to install but I don’t think there are other online replacements for Calsky currently.

Thanks for that.

I don't have an android phone, and that's the most user-unfriendly website I've ever seen, but I'll see what it can do!

Actually, it looks like that app has potential. I found an android emulator which allows you to run android apps on your PC, so for only 89p I downloaded the app and got it running.

Sure enough, it predicts nearby transits of the sun, moon and planets.

However, I note that when comparing with transit-finder.com on the right-hand image below (which I know from experience is highly accurate) there's a discrepancy. As you can see from this screen grab, the path of the solar transit on 7th December is shifted west by a considerable margin, and the time is slightly different. Perhaps it's using out of date orbital data, as I know the ISS is regularly adjusting it's orbit to counteract drag as it skims the upper atmosphere.

Does anyone out there have experience of this app and its quirks?
