Corwin's Notes

=====

NGC 3040 is a triple system, though Stephan only measured and described the
brightest.  Holmberg has the brightest two in his catalogue of double galaxies
from 1937, though does not note the NGC number.  His number is Ho. 148 for the
pair; Ho. 148a is NGC 3040.

Steve's Notes

=====

NGC 3040

17.5" (4/9/99): faint, fairly small, elongated 2:1 NNW-SSE, 0.8'x0.4'.  Fairly well concentrated with a bright, round 20" core and faint extensions.  A mag 14 star lies 1.8' SSE.  Brightest in a triple system, including Ho 148b at the northeast edge (companions not seen).

CGCG 92-065, located 12' N, appeared extremely faint, very small, round, 15" diameter.  Contained a stellar nucleus in moments of steady seeing.
