    With the recent launch of the new Iridium sats i checked to see if they
    would flare or not. The latest Iridium.tle had them listed numerically so i
    changed them to Iridium A - E like they are in McCants.tle and i got a
    prediction for a -4 flare from Iridium A 27372 02005A for this evening (Mar
    1 UTC). I think the designation should be B as the sequence is B-A-C-D-E
    unless B and A take turns leading. Anyways i went out and despite a hazy
    moonlit sky i saw Ir A/B begin to flare at 04:42:57 1 Mar UTC +/- 3 sec. Az
    10 deg El 25 deg. It gradually brightened to approx mag -8 and stayed that
    way for about 10 sec while the entire flare sequence lasted over 30 sec. I
    didn't really time it but it was long.
    
    About 10 min later Ir 60 25276 98019E flared to a -6 but it was pale
    compared to the earlier one.
