Renaming article
[edit]If this object is not actually a galaxy, perhaps the article can be renamed "Snickers(supershell)", "anti-center shell" or some other descriptive name. --George100 (talk) 05:37, 5 June 2008 (UTC)
Coordinates: what about them?
[edit]In this article is written the anticenter shell is in Auriga constellation, but at DEC=-15°, or l=197°. Well: Auriga is a northern constellation (impossible DEC=-15°); l=197° is about DEC=+12°, in Orion constellation (near the border with Monoceros, -Uranometria 2000, Sky Atlas 2000...). The southernmost point of Auriga constellation is +28°. Which measurements are correct? --Roberto Segnali all'Indiano 04:41, 20 October 2008 (UTC)
- The RA and declination given is in Canis Major. Maybe somebody misread it? If it's at 15 north rather than south declination, then it would be in Gemini, near the Orion border. Can anybody straighten this thing out? Methychroma (talk) 23:21, 25 March 2010 (UTC)
- Perhaps the –15 comes from interpreting the hyphen in the name "0627-15" as a minus sign? Burnham describes it (p. 837, under Dorado, in his discussion of the LMC) as "8 degrees NE of Betelgeuse", which would agree with +15, putting it in Gemini. See also this link: Whatever became of Snickers? by Richard Pogge at Ohio State. (Pogge puts it in Gemini, or more generally in "the Orion-Gemini region".) Astroprof puts it in Auriga; either he's being careless, or it's a big object. Consensus seems to be that it's not a galaxy but a gaseous region of the Milky Way, though not conclusively decided either way. -- Elphion (talk) 23:11, 30 January 2013 (UTC)
- I haven't found yet a definitive statement of the equatorial coords, but the research available on line all agree on the galactic coords (197, +2), which in J2000 is roughly 6h 29m, +15°. 6h 27m in the article is probably B1950. I've left 6h 27m intact, but changed −15 to +15. "Auriga" is a red herring: that's where the anticenter is (barely), not the shell -- Elphion (talk) 17:58, 18 March 2013 (UTC)
