Object name: ARP162
Arp 162/NGC 3414, located in Leo Minor about 80 light-years away is one strange galaxy. Arp put it in his galaxies with diffuse elements (filaments). It shows a huge halo and a diffuse disk. NED classes it as S0 pec. Modern rotational measurements show an interesting twist. The inner parts of the galaxy rotate one direction with maximum measured velocities along the disk as you'd expect but once you get out further suddenly the velocities slow and then reverse! But now are aligned on a different axis rotated 10 or 15 degrees counterclockwise from the disk. See http://articles.adsabs.harvard.edu/cgi-bin/nph-iarticle_query?2004MNRAS.352..721E&data_type=PDF_HIGH&whole_paper=YES&type=PRINTER&filetype=.pdf for the velocity map and other information. They draw no conclusions. I would suspect this is an indication of a merger. That would explain most of the features. The galaxy was discovered by William Herschel on April 11, 1785. It is in the original Herschel 400 observing program. I don't understand my notes from that, however. They were made on April 16, 1985 at 100x with my 10" f/5 under humid conditions. That apparently limited my ability to see faint objects as my entry reads "Small, round galaxy. Faint but easy due to its small size. A star-like nucleus seen with averted vision." Obviously, I was seeing only its center portion due to the conditions being worse than I realized.
