Corwin's Notes

=====

NGC 2897 has a beautiful companion galaxy with a nearly circular ring, almost
exactly centered on the nucleus.  These ring galaxies are relatively rare, but
can be pretty well-explained by the face-on, centered collision of two 
galaxies.  Theys and Spiegel (in ApJ 208, 650, 1976) were among the first to
try to explain these ring galaxies in terms of a collision, and their model 
has held up reasonably well over the years.

Steve's Notes

=====

NGC 2897

17.5" (3/7/92): very faint, very small, round, 15" diameter, low surface brightness.  Located just 1.8' WNW of mag 8.0 SAO 117736 which detracts from viewing.  Forms a pair with NGC 2898 8' S.  Not listed in the CGCG, UGC, MCG or RC3 although 15th magnitude.
