    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 morning. Some comets brighter than about mag 14.0 will be visible; we list them below, based on the JPL List of Currently Visible Comets (also note 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.
    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
    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 objects.

    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.

    Also, meteors from various showers may occur, and depending on your location, you may be able to observe the International Space Station, ISS.
