In looking more closely at this, it should also be noted that for the
03:44 UTC maxima -- presumed to be composed of debris ejected from
55P/Tempel-Tuttle in 1733 -- the Leonid radiant will be at, or just above the
east-northeast horizon for New York City and all points to the north and east
(in NYC the radiant will in fact be rising at 03:44 UTC, the altitude being
zero degrees). While obviously much too low to make any meaningful counts,
this nonetheless brings up the possibility of catching a few "earth-skimming"
Leonids emanating from out of the east-northeast sky. One would have to
hope, however, that in 2000 such meteors are brighter than 1999; last year
those along the US East Coast who searched in vain for earth-skimmers were
frustrated by the faintness of most of the Leonids . . . atmospheric
extinction pretty well squelching their visibility until the radiant reached
well-above the horizon.
Of course, this year we also have the !@#$* Moon to contend with too!
