  UGC 05814 - 22” f/4.1 (203, 293 and 377x) — This Arp is a low surface brightness round smudge. Even surface brightness throughout its 45” diameter surface. A 12.3 magnitude star lies 1.1 SW. A ?bright” 8.1 magnitude star lies 5.2? SSE. This galaxy was tougher than expected, but moving the 8.1 mag star off the field made it a lot easier to see. Alvin Huey

  PGC 32899 CGCG 314-001 - 30” f/4.3 @ 290, 419 and 754x (NELM: 6.8, T: 8/10) At 419 and 754x, this challenging group of four galaxies was seen. The two brightest ones were seen instantly, but the other two required a 5mm eyepiece to see its two very faint nearly stellar spots. Component A (PGC 32899) - This galaxy is small and considerably faint. Its round disk is about 10” across. Component B (PGC 32895) - This member is small and considerably faint. It is a tiny bit fainter than PGC 32899, which lies less than 30” NE. Estimated size is about 10”. Component C (PGC 32893) - At 754x, this member shows a very small almost stellar spot. Its very faint disk is less than 5” across. Sits about 25” due west of PGC 32895. Component D (PGC 32890) - At 754x, this member shows a very small almost stellar spot. Its very faint disk is less than 5” across. Located about 25” SE from PGC 32893. - Alvin Huey

  NGC 3556 - 18" (5/14/07): very bright, very large, elongated 4:1 WSW-ENE, ~8'x2'. This striking galaxy has a very mottled, patchy appearance with the main body appearing twisted or distorted. A few brighter patches or knots are visible along the major axis with a prominent knot along the west side. The core region is streaked with dust. The brightest portions of the two extensions have slightly different orientations or central axes! The galaxy bulges out a bit on the east end and the galaxy appears to bend a bit towards the north on the west end adding to the asymmetry. A couple of faint stars are superimposed on the eastern extension and close to the center is a prominent mag 12.5 star masquerading as a bright, stellar nucleus. The Owl Nebula, M97, lies 48' SE.

  PGC 34447 - 30” f/4.3 @ 538, 754 and 1256x (NELM: 7.0, T: 9/10) This was an impressive challenge for me in the 30-incher. The brightest member is at magnitude 18.7! I saw two of the five members at 754 and 1256x. Two other observers confirmed this observation. Component A (PGC 34447) and Component B (PGC 34452) were seen as a bipolar elongated patch. Not quite resolved. Component E (PGC 34453) was suspected as an extremely faint patch attached to PGC 34452. The position angle of PGC 34447 and PGC 34452 is directly E/W. PGC 34447 was about 10” from a magnitude 16 star. Component C (PGC 34444) and Component D (PGC 34448) were not seen. - Alvin Huey

  There are actually two galaxy clusters superimposed on the sky here, according to the NASA Extragalactic Database (NED). AGC1213 is around 700 million light years away, while AGC1213A is much closer at 400 million light years. A pair of nearby 10th-magnitude stars make galaxy identification pretty easy in this cluster. The brightest member is UGC6292 at mag 14.4 but the area about five arcminutes south from UGC6292 appeared very clumpy and may be the central concentration. At times I thought I glimpsed a couple of 15th magnitude MCG galaxies there. It was easier to spot the two brightest galaxies in AGC1213A just to the north. - Jim Shields

Listed as N3561A/B in the RC3 (M+05-27-010, M+05-27-011), 0.7x0.7 and 0.9x0.9 although only the southern member should be credited to JH.

In Scientific Papers, Dreyer states this number should probably be rejected "as there was fog which indeed was so strong as make everything swim to me." The NGC position is exactly 1.0 tmin W and 3' S of U06134 = M+01-28-033 = Arp 335. Sinnott claims the RNGC RA is incorrect (off by 1.0 tmin) but the RNGC RA matches U06134.
