Messier Marathon 2016 (original) (raw)

2016 Messier Marathon Results

In the year 2016, New Moon will occur on March 9 and April 7, so the best Marathon time in mid-March will be prevented by the Moon. There will be two opportunities for Messier Marathon, the first and primary on March 12/13, 2016 where M30 will be extremely difficult to impossible from most locations, and April 2/3, 2016 where it will be extremely improbable to succeed in finding the first evening objects, M74 and M77. According to Tom Polakis' investigation, on the first primary occasion, a full score of 110 Messier Objects should be possible from locations between 9 deg and 27 deg Northern Latitude with most difficult object M30 in the morning, and southern limit from M52, while on the secondary date in April, the probable invisibility of M74 will make it so unlikely.

Messier Marathon Events 2016

Again, we plan to announce all scheduled 2016 Messier Marathon Events here.

Martijn Straub of Holland is planning his first Messier Marathon during the week of March 7-11, 2016 from the Mirador de los Andenes in La Palma. He will do this with a 15x70 binoculars on a tripod.
The 2016 All Arizona Messier Marathon is scheduled for the weekend of March 12/13, 2016. This event is sponsored again by the Saguaro Astronomy Club (SAC) (for the 24th time). It will be held at the same site as last years, the Salome Emergency Airfield (a.k.a. "Hovatter Airstrip"), an abandoned airport, about 100 miles west of Phoenix. - A.J. Crayon, Rick Tejera, & Jack Jones
Also see SAC's 2016 All Arizona Messier Marathon announce, and their All Arizona Messier Marathon facebook page.
The Mauna Kea Messier Marathon 2016 is scheduled for the night of March 12/13, 2016 at the Ka'ohe observing site, organized and sponsored by the West Hawaii Astronomy Club and lead byAndrew Cooper. Participants and guest observers are invited to join. Andrew will provide a Messier Marathon observing list adjusted for their latitude of 20d N. The site is situated along the old Saddle Road, just above the Kilohana hunter check in station; the precise location can be found on Andrew's website. - Andrew Cooper
The SPACE Messier Marathon 2016, first half of 55, is scheduled for March 5-6, 2016 in Tehla, Rajastan by 18 astronomy educators. Live updates will be posted to twitter - see announce above. This event will be sponsored by the Education Department, SPACE. (contact) - Vikrant Narang
TheSan Francisco Amateur Astronomers (SFAA) and the San Francisco Sidewalk Astronomers will host again an apparition of Charles Messier (actually Kenneth Frank dressed) on Mount Tamalpais in Marin County, California, USA, and join for holding a Messier Marathon on April 2, 2016. - Kenneth Frank (nee Charles :) ) Please submit any scheduled events for announce here.

If you have undertaken, or participated in, a Messier Marathon, 2016 or earlier, if not already done so, please send me your or your group's results, or the link to your results page, for inclusion in our Messier Marathon Results page!

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 impossible this year 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 13, 2016 April 3, 2016

10P/Tempel 2 00:59:41 -02:25.6 13.9 01:49:48 +02:39.7 14.8 C/2013 US10 Catalina 04:11:30 +53:54.0 9.2 04:25:13 +49:37.6 10.3 81P/WIld 2 05:24:41 +21:38.3 12.8 05:56:31 +22:30.8 12.6 252P/LINEAR 05:51:24 -51:08.8 11.5 17:34:12 -07:55.4 12.2 9P/Tempel 1 12🔞20 +19:14.2 13.4 11:58:25 +20:53.4 12.6 116P/Wild 4 15:51:21 -21:26.4 12.3 16:00:11 -22:42.4 12.2 53P/Van Biesbroeck 19:19:55 -16:54.9 14.6 19:56:19 -15:23.0 14.3 29P/Schwassmann-Wachmann 1 19:36:12 -25:58.4 15.8 19:47:15 -25:33.8 15.7 Outbursts! c. 11m C/2014 W2 PANSTARRS 20:34:31 +65:38.7 14.0 20:20:48 +68:16.1 14.0

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, only (3) Juno will be in favorable oserving situation, but faint. (1) Ceres will be close to the Sun and thus impossible, while both (4) Vesta and (2) Pallas will be difficult objects in the evening and the morning sky, respectively. 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 13, 2016 April 3, 2016

(1) Ceres 23:25:10 -12:22.8 9.0 23:55:44 -09:15.3 9.2 (2) Pallas 20:52:28 +05:27.7 10.6 21:15:03 +07:24.6 10.6 (3) Juno 15:01:30 -05:46.5 10.5 14:53:57 -04:18.5 10.3 (4) Vesta 02:05:18 +07:39.1 8.4 02:38:40 +10:58.8 8.4

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