Corwin's Notes
=====
NGC 3545 is a double interacting galaxy. The components are approximately
equal in brightness as judged in DSS images, so I wondered which one Stephan
saw in March of 1884 when he found the object. Re-reducing his micrometric
position suggests that he measured the western galaxy. While he does not
mention the eastern galaxy explicitly, he does suggest that his object may be
resolvable ("... semble resoluble.")
On the same night, he found NGC 3542; his position for that, measured with
respect to the same comparison star, HD 97287, is within 0.6 second of time
in RA, and half an arcsecond in Dec, of the SDSS position. This suggests that
his measurement of NGC 3545 really does apply to the western galaxy.
Steve's Notes
=====
NGC 3545
17.5" (3/12/94): faint, small, round, 40" diameter, slight even concentration. Forms a trio with NGC 3542 3.5' WSW and MCG +06-25-014 4.7' NW. MCG +06-25-015 lies 10.5' NNW. This is a double system with components separated by just 13" (oriented SW-NE).
