Description:
These observations were recently made while waiting for Hale-Bopp to rise!
Included are detailed notes of several challenging Hickson groups including
Hickson 30, 31, 32, 34 and 37 and 38. Observing aids included Hickson's
CCD images from the Canada-France-Hawaii telescope, Megastar-generated
finder charts and digitized images downloaded from SkyView.

Hickson 37a = N2783
09 13.7 +30 00
17.5 (2/8/97): brightest of three galaxies visible in Hickson 37. Fairly
faint, fairly small, elongated 3:2 NNW-SSE, bright core. Two mag 9.5-10
stars lie 1.4' SW and 2.2' SSW. U04856 = Hick 37b is 1.5' WNW and just off
the NW side is a marginal member Hickson 37c, 36" from center.

Hickson 37b = UGC 04856
09 13.5 +30 00
17.5:second brightest of three visible in Hickson 37. Appears very faint,
fairly small, elongated 2:1 or 3:1 E-W (difficult to determine due to very
low surface brightness arms). Only core noticed at first glance,
extensions require averted vision to see well. Located 1.5' WNW of N2783.
Hickson 37b is 1.0' E of center.

Hickson 37c = M+05-22-020
09 13.6 +30 00
17.5:faintest of three seen in Hickson 37. This object was at the
threshold of visibility and required averted vision to glimpse at moments.
Appeared extremely faint, round, 10" diameter. Located just 0.6' NW of the
center of N2783 = Hickson 37a (in outer halo on photos) and 1.0' following
the edge-on U04856.
