Lassen observations

UGC galaxies in Cygnus

by Steve Gottlieb


Wednesday night at the Devastated parking lot I spent a couple of hours working on UGC galaxies which are buried in the Cygnus milky way. A number of these are also described in Jay McNeil's article in July S&T. One of my favorite fields was the UGC 11465 group -- three faint galaxies in the same high power field as the bright double star 16 Cygni (close to the blinking planetary) which Mark Wagner also observed from the Bumpass lot. I also chased down a number of faint galaxies in eastern Virgo and Libra ...

UGC 11421 = M+07-39-020 = Z229-032
19 15 33.5 +44 06 20
V = 13.1; Size 1.2x1.2; SB = 13.3

17.5" (6/28/00): faint, fairly small, round. Appears to have an 11th magnitude star superimposed which makes the observation difficult. Centered in an oval ring of 6 mag 11/12 stars. The milky way field is very rich and it was very difficult to match up the GSC finder chart.

17.5": faint, fairly small, round.


UGC 11459 = M+07-40-011 = Z230-024
19 37 22.7 +40 42 20
V = 13.4; Size 2.2x1.3; SB = 14.4; PA = 12d

17.5": faint, fairly small, elongated 3:2 N-S, 1.0'x0.7', low even surface brightness. Three mag 13-14 stars are off the SE flank. U11460 lies 19' NNE.


UGC 11460 = M+07-40-012 = Z230-025
19 37 51.7 +41 00 33
V = 12.9; Size 1.4x0.8; SB = 12.9; PA = 120d

17.5": faint, very small, slightly elongated WNW-ESE, 35"x25", very small brighter core. Located within a string of faint stars (three are collinear off the following side). Set in a rich Cygnus star field 15' following a string of three mag 7-8 stars. U11459 lies 19' SSW.


UGC 11465 = M+08-36-002 = Z257-006
19 41 42.3 +50 37 56
V = 12.8; Size 1.2x1.2; SB = 13.0

17.5" (6/28/00): fairly faint, small, round, 25" diameter, weak even concentration to a very small brighter core. Brightest of close trio with M+8-36-3 2.3' SSE and PGC 63532 just 0.8' SSE. In the same high power field with the bright double star 16 Cygni!

17.5": fairly faint, fairly small, round, small bright core. Located 7' N of the striking double star 16 Cygni = 6.3/6.4 at 39". Forms a pair with M+08-36-003 2.3' SSE.


PGC 63532
19 41 44.7 +50 37 15
Size 0.2x0.15

17.5": extremely faint and small, round, 5"-10" diameter. Picked up with averted vision close SSE of U11465 [47" SSE of center] about 1/3 of the way on a line to M+8-36-3.


MCG +08-36-003 = Z257-007 = 3C 402
19 41 46.0 +50 35 45
V = 13.8; Size 0.8x0.7; SB = 12.9

17.5" (6/28/00): faint, very small, round, 20" diameter. Contains a small, slightly brighter core. Second brightest of trio with U11465 2.4' NNW and PGC . Located just 4.3' N of 16 Cygni.

17.5": located 4' north of the striking double star 16 Cygni! (6.3/6.4 at 39"). Faint, small, oval, even surface brightness. Forms a pair with brighter U11465 2.4' NNW.


UGC 11466 = Z257-008
19 42 58.8 +45 17 58
V = 11.7; Size 2.0x1.2; SB = 12.5; PA = 35d

17.5": fairly faint, elongated 3:2 SW-NE, 1.2'x0.8', gradually brighter halo, small bright core. Located 3.5' W of a double star mag 10/12 at 19" separation in a rich milky way field. Delta Cygni (V = 2.9) lies only 23' SE. This is a bright UGC galaxy located just 10.8° above galactic plane.


UGC 11485 = Z257-014
19 48 59.6 +50 18 47
V = 13.1; Size 1.3x0.7; SB = 12.8; PA = 25d

17.5": faint, small, elongated 2:1 SW-NE, 40"x20". A small trapezoid of mag 13-14 stars is close SE.


UGC 11492 = M+10-28-015 = Z303-015
19 52 40.0 +57 27 35
V = 13.5; Size 1.7x1.0; SB = 13.5; PA = 70d

17.5": faint, moderately large, slightly elongated, 1.2'x1.0', very weak concentration and no noticeable core. Located 6' SW of mag 5.1 23 Cygni which detracts from viewing. Set in a rich milky way field.


UGC 11500 = M+08-36-011 = Z257-024
19 57 02.0 +50 10 52
V = 13.9; Size 1.0x0.8; SB = 13.4

17.5": very faint, small, elongated 4:3 ~N-S, 40"x30", low even surface brightness. Forms a pair with M+8-36-9 just 0.8' SW (not seen) and brightest in a quadruple group.


UGC 11503 = M+08-36-012 = Z257-027
19 58 42.4 +50 02 12
V = 12.8; Size 0.9x0.7; SB = 12.2

17.5": faint, very small, round, 25" diameter. A faint stellar nucleus is visible with direct vision. Bracketed by two mag 13/14 stars [0.9' NW and 0.8' SE] and set in a rich Cygnus star field.


UGC 11775 = M+06-47-004
21 35 48.2 +35 21 03
V = 13.1; Size 1.0x0.4; SB = 12.0; PA = 50d

17.5": very faint, very small, slightly elongated. The image is hampered and confused by a mag 13.5 star which is superimposed on the SE side so viewing requires concentration. Located 4.2' SE of IC 1392.


UGC 11781
21 36 39.5 +35 41 40
V = 12.1; Size 1.4x1.1; SB = 12.4; PA = 75d

17.5": picked up while searching for IC 1392/U11775 23' SW. Faint, very small, round, 20" diameter, very weak even concentration (based on DSS image, only the core was viewed and not the SW-NE wings). A mag 13 star lies 1.2' NE.


UGC 11804 = M+08-39-002a = (Z544-003)
21 44 09.9 +46 14 47
Size 1.5x0.6

17.5": this interacting double system (with U11805) appeared very faint, small (probably viewed core only). Closely bracketed by a close pair of mag 13 stars at the SW edge and a mag 12.5 star to the NE. At moments, there is strong impression of the close companion attached to the mag 12.5 star [just 32" between centers]. Very difficult to track down as situated in a rich milky way field with a patch background.


UGC 11805 = M+08-39-002b = (Z544-003)
21 44 12.0 +46 15 10
Size 1.5x0.4; PA = 136d

17.5": NE member of a faint interacting pair with U11804. Very difficult to untangle this pair in a rich milky way field and furthermore this member of the pair appears to have a mag 12.5 superimposed. At moments there was an extremely faint, elongated glow attached to this star.
