Re: (meteorobs) unexpected bursts

Agree with Kim that observing on the day before and
after the peak would be worthwhile. In 1998, I
observed a day before the predicted peak of the
Leonids in Manila, and was blessed with large numbers
of fireballs.  The number of fireballs the day before
the peak made the real peak the following day more of
a let-down as the number of fireballs decreased.
