    Very interesting. Something like this happened during the last few days
    of MIR. I was observing about 15 km away from a friend and I told him to
    run outside and see if he can catch it. He did, but in the few seconds
    it took to make the call and to get outside, MIR was already low in the
    horizon. Iridium flares would be more challenging to observe this way.
    I think we need to come up with a list of people on the flare path and
    organize days before the event. It would also help if we use a broadcast
    network (VHF/CB/SW ?) in addition to cell (person to person)

    What would be even more interesting is once we get enough PDA's
    wirelessly, you could potentially make a network of people observing
    satelites.  Of course you'd need quite a few people in the same area to
    advantage of it.  It would potentially allow people to be alerted
    before an observed passover...
