    Very bright flashes indeed! They were hard to miss. I thought
    it was a plane but there were no other strobes or beacons.
    When I saw the second flash I knew it had to be a sat.
    I've been in email contact with Bjorn Gimle and from the
    map he provided I concur that IRS-P2 is the likely candidate.
    I looked again using the TLE files I had and I find a good
    match to IRS-P2. It didn't show up in my postdictions last
    night because I had the filters set wrong. duh....
