    Hi Tom,
    Everyone has their favourite. Mine is Orbitron and by coincidence I have it running at the moment with Calipso highlighted with ground track selected. Yesterday I even went out at 3:00 pm local time and looked up into the dazzling white cumulus half expecting to see one of the clouds suddenly change to green! (I jest, but wouldn't that be great to see!)
    I used Orbitron (free download from to spot Suitsat and that was not an easy object to see from Canberra.
