Corwin's Notes
=====
NGC 7813 is probably identical with IC 5384, though the descriptions do not
match, and Muller's position is a typically poor one from the second Leander
McCormick list in AJ. The IC number comes from Howe who found the galaxy
while looking for NGC 7813. The position angles for the galaxy (Muller, 80
deg; Howe, 160 deg) and surrounding stars (Muller, "*8.5 f 38s" and "*9 np
40s"; Howe "*8.5 p 49s" and "two sts 9 nnp") don't match, but the declinations
are the same as are the general descriptions "eF, vS, E".
I do see a somewhat fainter star (about 10th magnitude) roughly 25 seconds
following the galaxy -- is this possibly Muller's "* 8.5"? Unfortunately, he
has left us no sketch.
The IC identification, at least, is secure.
Steve's Notes
=====
NGC 7813
17.5" (11/6/93): very faint, very small, round, weak concentration, can just steadily with direct vision. A mag 13 star is 3' NW. Located 12' ESE of mag 8.2 SAO 147055. The listed magnitude appears too bright.
