I am begining preparations for my Astronomy column on comets, when I came
across the return of 73P/Schwassmann-Wachmann 3 that will occur this
upcoming June. However, it broke apart during its last return, and Gary
Kronk's meteor page suggests that we should be on guard for a possible
(large) jump in meteor activity in early June.
Any thoughts from the experts on the list? Using the 3-D Java applet from
NASA I get a plane crossing just after May 30, but that method is far from
precise. Also, trails can be picked up a few days on either side on
favorable revolutions.
Sorry the event is so far from now, but publishing deadlines are almost a
1/2 year in advance (I am writing March right now).
While the comet might put on an interesting show during the middle part of
May 2006, odds are that we will not see much, if any meteor activity . . . at
least at this upcoming apparition.
Comet 73P fragmented into four separate pieces in 1995 and the massive
expulsion of dust/debris shed from this fragmentation ultimately should pass very
close to the Earth,
but not until 2022!
Two of these pieces were definitively seen when the comet returned to the
inner solar system in late 2000. Interestingly, on May 17, 2006, at 6:41 UT, one
of these fragments is
predicted to pass just 4.8 million miles from Earth. Some forecasts suggest
that a larger fragment might even briefly reach second magnitude during
mid-May.
The dust trail from the 1995 fragmentation should pass very close to Earth
and on May 31.205 (UT), in the year 2022. This trail will pass just 0.0004
a.u. from Earth and might very well produce a significant meteor outburst.
What's more, the Moon will be new at that time!
The full details can be found in WGN 29-1/2, February-April 2001, pp
15-28. This well-written paper was authored by Hartwig Luthen, Rainer Arlt,
