Corwin's Notes
=====
NGC 6637 may possibly also carry the number NGC 6634, which see. This is
unlikely, in my opinion, but still possible.

NGC 6637
17.5" (7/29/92): M69 is bright, moderately large, 3' diameter, round, fairly symmetric appearance with a large core surrounded by a small halo. A bright mag 12.5 star is embedded in the core or contains a bright stellar nucleus. Several easy mag 13.3-14.0 stars are resolved around the edges of the halo and 15-20 very faint mag 14-15 stars are visible in the halo with averted vision. Additionally, a few stars are also detected over the core. This is a pretty globular with averted vision. Located 4.5' SE of mag 7.9 SAO 21059.
8": fairly bright, bright core, lively halo, few stars at edges, difficult to achieve resolution.
15x50mm IS binoculars (8/3/11): small, fairly faint glow. The mag 7.9 star 4.5' NW was cleanly resolved from the globular.
