lol you must be psychic Newark777, I was going to post a topic on the same subject.
Here in the UK tonight theres clear skies, and I logged into Heavens-Above and found that Envisat was transiting the moon at 22.16.
So I go out at 22.00 to set up the scope, and with the moon being at 93% it was a perfect clear night (still is infact..I just come in to warm up a bit.)
Exactly a second after it was due to transit the Moon the Satellite whizzes past literally in the blink of a eye it had crossed the Moons "face".
And also saw 2 other Satellites which were COSMOS 2219 and METEOR 1-29 within a minute of each other.
Im currently staying up to see a double pass by the ISS, one at 03.39 and the other (slightly brighter) around 0500am.
But yes if your into Satellites or Flares like I am, Heavens-above is well recommended, also the star charts and "Comet finder" comes in handy too.
Its not the fall that kills u, its the sudden stop at the end..
