Re:PGC 044847
pgc0044847 detected in the beam of pgc44854, 12' Southwards from the
center. Assymetrical profile due to misalignment in RA

Re:NGC 4902
NGC 4902.---SB(r)b: Centrally condensed bulge. Outer bulge isophotes
are elliptical. A prominent bar is slightly skewed with respect to the
bulge major axis. Bright stellar feature in/imposed on SW side of bar.
Bar ends in a pronounced inner pseudoring. After ~150deg of winding,
spiral arms break away from the ring (the ring is complete, but the
final ~30deg on either side is much fainter). At least two fainter
arms emerge earlier from the ring, the more prominent of which emerges
at a clear kink on the north side of the ring. The arms are diffuse
and patchy.

Re:NGC 4902
NGC 4902 (SBb, 1"~170 pc, I=25.1^deg^)
The PA inside the large-scale bar (e_max_=0.60 at a=25") is approximately
constant (within 10^deg^).

The apparent internal ring in NGC 4902 is
the overlapping of two very bright arms of the
NGC 1300 type which begin at opposite ends of
the bar. Sets of other outer arms also exist, the
brightest of which is semi-detached from the
bright main inner arm (at the bottom of the print
on the facing panel).
Many HII regions exist in the bright parts of
the several arms and the arm fragments.
NGC 4902 is kinematically associated with
a loose group that includes NGC 4899 (Sc; panel
232), 34' to the north, NGC 4891 (SBbc; panel
205), 64' to the north, and several other probable
members listed in the RC2. The redshifts are
v_o(4891) = 2418 km/s, v_o(4899) = 2437 km/s,
and v_o(4902) = 2426 km/s. At a mean
redshift distance of 48 Mpc (H = 50) the
projected linear separations from NGC 4902 are
480 kpc and 903 kpc for NGC 4899 and NGC 4891,
respectively. This aggregate, then, has a
size nearly the same as the Local Group.
