Corwin's Notes
=====
NGC 3531 = NGC 3526. Holden misidentified the star he noticed 46.5 seconds
preceding the galaxy. When the correct star is used (BD +7 2412, not 2413 as
Holden wrote), his position falls close to that of NGC 3526 = Marth 215. The
descriptions are virtually identical, and Holden notes the star just southwest
of the galaxy.
Spitaler was the first to suggest the identity. He found IC 670 near Holden's
position, but that is fainter and does not agree with either of the earlier
descriptions, so Spitaler -- correctly -- called IC 670 a "nova."
