UGC 9480 82" Otto Struve Telescope

Moderately bright, fairly large, elongated 3:2 WSW-ENE, 0.8'x0.5', bright core. Observation made through clouds.

NGC 5258 82" Otto Struve Telescope

NGC 5258 is the eastern member of a dramatic interacting pair (Arp 240 = VV 55) with NGC 5257 directly west. The two galaxies are connected by a very low surface brightness bridge that spans the eastern spiral arm in NGC 5257 and the western arm in NGC 5258. NGC 5258 was strongly concentrated with a bright, mottled core. There was a bright region in the spiral arm to the north of the core, midway to a mag 15.5 star. An obvious spiral arm swept east from the south side of the galaxy. The northern arm is much less evident, mainly just south and west of the mag 15.5 star, but immediately dims into a very low surface brightness bridge stretching to the NGC 5257.

NGC 5257 82" Otto Struve Telescope

The view under subpar conditions in the 82" was similar to the view 3 years ago in the 48". The most striking feature are two thin bright spiral arms that appear as very bright arcs, like two parentheses enclosing the fainter central region. A diffuse tidal arm extends from the north side to the NE and nearly reaches a mag 15 star. On the SW side a very low surface brightness "bridge" connects NGC 5257 with NGC 5258.

NGC 4898 82" Otto Struve Telescope

The brighter southwestern component of NGC 4898 appeared bright, fairly small, round, very bright nucleus. It was very easily resolved from the northeastern component [separation 7"].

NGC 4889 82" Otto Struve Telescope

Extremely bright, large, oval 4:3 ~E-W, very strong concentration with a very bright core and an intensely bright nucleus. The halo extends ~1.8'x1.4' and fades out slowly. PGC 44708, an edge-on galaxy, poked out of the west side of the halo towards the NW. It appeared fairly faint, extremely thin, perhaps 7:1 NW-SE, ~28"x4".

IC 4011 82" Otto Struve Telescope

Fairly bright, fairly small, round, 15" diameter, very small, very bright nucleus. Situtated just 1.6' NNW of NGC 4889 in the core of AGC 1656.

NGC 4676 82" Otto Struve Telescope

The tidal tail north of IC 819 (NNW member of the interacting "Mice" (NGC 4676)) was very prominent as a direct vision streak, extending at least as far as the mag 17.3 star situated 1.6' due north of the center of the galaxy.

IC 3137 82" Otto Struve Telescope

Low surface brightness, thin edge-on, 5:1 oriented SW-NE, ~40"x8". Forms a line-of-sight pair with IC 3138 1.5' SSW.

Pal 3 82" Otto Struve Telescope

Observed under poor seeing and transparency at 400x; very faint hazy glow visible, mostly evident at the center (core) of the cluster. Three extremely faint stars (mag 18-18.5) were occasionally resolved.
