Serpens Caput

(All Positions are J2000)

NGC 5919  (15h 21.6m  +07° 44')
Swift's position is 10s W of M+01-39-020 = Z049-142 at 15 21.5 +07 43
(2000).  The listed dimensions of 3.0'x2.0' in MCG and 3.3'x2.2' in RC3
must refer to a combined size for several galaxies.  There are at least 6
small nearby galaxies on the POSS so the ID is not certain but based on
this visual observation it appears likely that N5919 = CGCG 049-142 
(triplet?). It is possible that my observation of a 2nd or 3rd object 
includes CGCG 049-144 which is only 1' ENE.

Harold Corwin came to the same probable conclusion regarding ID's.  DSFG
gives 11.4V which is much too bright (PGC has 12.4B).  GSC position 
15 21 36.9 +07 43 10.

N5942  15 31.6 +07 19
Discovered by Swift in a compact group. This gx is identified as N5941 in
RNGC, CGCG, MCG, RC3, U2000 and DSFG!  These catalogues identify N5942 as
HCG 76d which is likely an anonymous gx (not found by Bigourdan).

Based on my visual observation of the 4 members in the group I suggested to
Harold Corwin that the ID of N5941 was in error which led to his reassignment
of ID's bases on Bigourdan who only observed the 3 brightest gx's (HCG 76b,76c,
76a).

Bigourdan stated that the orientations of N5941/5942 were nf/sp which
places N5941 slightly east of N5942.  GSC position 15 31 36.9 +07 18 44.
