Messier Marathon 2019 (original) (raw)

2019 Messier Marathon Results

In the year 2019, New Moon will occur on March 6 and again on April 5, so that the best Marathon time in mid-March will be prevented by the Moon. There will be two opportunities for Messier Marathon, the first on March 9/10 and the second, primary for mid-northern observers, on March 30/31, 2019. On neither of these dates, a full score of 110 will be easy for mid-nothern observers. According to Tom Polakis' investigation, on the first date (March 9/10), the full 110 will be possible only between latitudes 9deg and 25d. N, limited by M52 and M30. On the second date (March 30/31), it will be theoretically possible between 18d. and 40d. Northern latitude, limited by M110 and M30, with M74 and M110 extremely difficult.

Messier Marathon Events 2019

Again, we plan to announce all scheduled 2019 Messier Marathon Events here.

• The 2019 All Arizona Messier Marathon is scheduled for the weekend of March 30/31, 2019. This event is sponsored again by the Saguaro Astronomy Club (SAC) (for the 27th time). It will be held at the same site as the last years, the Salome Emergency Airfield (a.k.a. "Hovatter Airstrip"), an abandoned airport, about 100 miles west of Phoenix. - Rick Tejera

Extracurricular Activities

While it is the goal of the Messier Marathon to observe as many Messier Objects in a night as possible, it is sometimes convenient and enjoyable to combine the Messier Marathon with some other observational activities, in case some time is left during the night session. In the following, we propose some options to select from:

Deepsky enthusiasts can look for additional clusters, nebulae, and galaxies. While you can certainly pick and observe whatever you like, we also providea list of additional deepsky objects to select from (also available with data).

It is always delightful to add to the Messier Marathon the observation of as many of the planets as possible, with Uranus and Neptune at least extremely difficult on the primary weekend.

Some comets brighter than about mag 14.0 will be visible; we will list them below from various sources (e.g., IAU's Observable Comets page,Skyhound's Comet Chasing page,Gary Kronk's list of current comets, Seiichi Yoshida's Visual Comet lists for the northern andsouthern hemisphere, and the Fachgruppe Kometen list):

Comet RA (2000.0) Dec mag RA (2000.0) Dec mag March 10, 2019 March 31, 2019

78P/Gehrels 2 01:10:42.8 +07:15:42 13.9 01:58:26.1 +11:10:05 13.9 C/2018 Y1 (Iwamoto) 04:50:11.9 +34:16:51 12.9 04:26:02.9 +33:22:12 14.4 46P/Wirtanen 09:43:04.1 +42:44:15 10.9 09:58:36.9 +35:55:33 13.5 123P/West-Hartley 11🔞58.1 +31:45:40 12.7 11:04:14.7 +29:26:34 13.0 C/2017 M4 (ATLAS) 17:31:43.7 -22:54:15 13.7 17:20:32.7 -28:06:39 13.5

C/2016 M1 (PANSTARRS) 03:57:09.0 -58:02:11 12.7 04:28:21.9 -49:21:23 13.1

The last of these comets is only accessible for southern observers.

Note that occasionally comets become bright shortly (like Hyakutake in 1996, Hale-Bopp in 1997, Ikeya-Zhang and Utsunomiya in 2002), so check back for possible updates shortly before Marathon date. Also occasionally, a supernova of brightness available to amateur telesopes may have flashed up be spottable in time (like SN 1998S in NGC 3877, SN 2002ap in M74, SN 2006X in M100, SN 2012aw in M95, and SN 2014J in M82 in their years of appearance).

This year, of the "first" four minor planets, three will be easily available, while (4) Vesta will be probably impossible because of small elongation to the Sun. (3) Juno will be visible in the evening, (2) Pallas best around midnight, (1) Ceres in the morning. For those who want to try these objects, data for the two weekends in question are as follows:

Planet RA (2000.0) Dec mag RA (2000.0) Dec mag March 10, 2019 March 31, 2019

(1) Ceres 16:42:08.3 -16:01:11 8.5 16:52:25.4 -16:31:08 8.2 (2) Pallas 14:11:02.8 +07:58:26 8.1 14:02:31.9 +15:07:19 7.9 (3) Juno 04:42:29.1 +09:11:59 9.4 05:19 18.6 +12:02:41 9.7 (4) Vesta 23:22:15.1 -08:57:46 7.9 00:00 13.1 -05:09:06 8.0

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