Talk:IC 342/Maffei Group

Perseus 1 and 2
Regarding the distances that I just filled in, I can't tell for sure whether Perseus A is the same as Perseus 1 and Perseus B is the same as Perseus 2 (the letters being found on this page, and the numbers being found at which identifies 1 and 2 with KKH 11 and KKH 12, respectively).

I changed them to Perseus 1 and 2. Perseus A is 320 light-years away, so it is clearly not the same as Perseus 1. Eroica 10:18, 26 May 2006 (UTC)

Problems with the "Observing the IC 342/Maffei Group in the future"
I looked up the IC 342/Maffei Group at the NASA/IPAC Extragalactic Database (using the name "IC 342 Group"). The database shows that the galactic longitude of the IC 342/Maffei Group is ~140° (i.e. it is located in almost the opposite direction from the center of the Milky Way). The current version of the "Observing the IC 342/Maffei Group in the future" section suggests that the IC 342/Maffei Group is located at 0° (on the far side of the galaxy according to the text, or in the "obscured" region according to the diagram), which is incorrect. I am therefore removing the section.

The reall issue with observing the IC 342/Maffei Group is that it lies within the plane of the Milky Way, so the dust within the Mily Way's disk obscured the group. This is what should be described in the text. GeorgeJBendo 22:16, 29 October 2006 (UTC)

Membership list revision
I would like to revise the membership list using the Karachentsev reference currently in this article. I would also like to revise the table format to look like the tables for the M83 Group as well. If no one objects, I will do this starting 13 Dec 2006. Dr. Submillimeter 12:55, 8 December 2006 (UTC)

Revisions as of 29-30 Dec 2006
I have made a number of revisions to this page:
 * I removed the verbose discussion of the member galaxies from the introductory paragraph. It was redundant with the galaxy membership list.
 * I revised the galaxy membership list using a refereed scientific journal article. The older list apparently came from two websites created by amateur/ex-professional astronomers (see the following note).
 * I removed the links to the seds.org and Atlas of the Universe websites. These websites contained out-of-date information that would only confuse readers.
 * I added a lengthy discussion on dust obscuration. (One of this group's most notable attributes is that it is heavily obscured.)

Additional notes on looking up specific desginations in the NASA/IPAC Extragalactic Database (NED): For example, a search on "KK 35" in NED should be done using "[KK98] 35".
 * Objects labeled with "KK" may be found in NED using "[KK98]".
 * Objects labeled with "KKH" may be found in NED using "kkh".

Please contact me if you have questions. Dr. Submillimeter 21:19, 30 December 2006 (UTC)

New paper argues it is two separate groups
Need to wait for it to get through peer review mind:
