2005 Messier Marathon Results
Messier Marathon 2005
The year 2005 will offer an opportunity for the Messier Marathon on the weekend
of March 10-11, with new moon occurring on March 10.4. This time it will
probably not be possible to hunt down all 110 objects.
More information will be added here timely.
On this occasion, it will not be possible to combine an all-planet marathon
with the Messier event, but most planets will be visible; only Venus and
Neptune will most probably not be possible, and Uranus difficult in the
Some comets brighter than about mag 14.0 will be visible; we list them below,
based on the JPL
List of Currently Visible Comets
IAU's Observable Comets page,
Gary Kronk's list of current comets and the
Fachgruppe Kometen list):
Comet RA (2000.0) Dec mag mag
March 11, 2005 obs.
The list is RA ordered and thus in the sequence the comets might be observed
from evening through midnight to morning.
Notable are comets C/2004 Q2 Machholz, which had a nice show as a naked-eye
object in January 2005 and is slowly fading to about 6.6 mag but circumpolar
at Marathon time, as well as C/2003 K4 LINEAR at mag 9.6; these two, as well
as C/2002 T7 (LINEAR), C/2003 T3 (Tabur), and 9P/Tempel 1 are in good observing
situation. The other three are very close to the sun and difficult dusk or dawn
C/2001 Q4 (NEAT) 00:01.83 +54:15.1 13.0
29P/Schwassmann-Wachmann 1 00:43.67 +12:49.0 15.7 12.5 (has outbursts)
C/2003 K4 (LINEAR) 03:32.48 -16:13.7 9.6 10.5
C/2004 Q2 (Machholz) 07:12.74 +84:52.1 6.6 6.2
C/2002 T7 (LINEAR) 09:55.88 -10:54.0 13.5 13.4
C/2003 T3 (Tabur) 10:12.47 +41:40.5 13.8
9P/Tempel 1 13:29.82 +11:14.0 12.3 12.7
10P/Tempel 2 22:45.39 -12:04.8 10.9
Note that occasionally comets become bright shortly (like Hyakutake in 1996,
Ikeya-Zhang and Utsunomiya in 2002), so check back for possible updates
shortly before Marathon date.
meteors from various showers may occur, and depending on your
location, you may be able to observe the
International Space Station, ISS.
