Hi David,

Thanks for your observation of Superbird A -- I'll be using it to tweak
my spin axis and precession rate model.  (My current model had
your peak coming 4 minutes later than you observed -- not that
bad considering I only had one data point since 21 Oct 98).

Your observation is just in the nick of time, too.  Friday morning,
shadow exit isn't until 3:29, and your flash peak is probably around
3:28.  So it will be turning on abruptly, with flashes getting
progressively dimmer.  Flashes might appear a bit reddish due
to differential refraction.  After Friday morning, you're out of luck
for a while (like the U.S.).  --Rob
