Steve's Notes

===== NGC 3310 48" (5/16/12): extremely bright, fairly large, sharply concentrated with a large, very bright, slightly elongated N-S core, ~1' diameter. The core appears mottled with a couple of "stellarings" or small knots. The core is surrounded by a larger, much lower surface brightness irregular halo, extending the central portion to nearly 2'. An outer spiral arm is attached on the north side of the halo and was most evident near the halo. Occasionally, a very large, very low surface brightness looping arm was glimpsed, rotating 180 clockwise and ending west of the core, ~1.7' from center. 17.5" (1/19/91): very bright, moderately large. Unusual appearance as contains a very bright, very large central core with uniform high surface brightness with only a very faint, fairly small halo, elongated NW-SE. Located 10.4' SSW of mag 5.5 HR 4165 at the edge of the 220x field. A mag 12 star lies 3.0' N.
