Corwin's Notes
=====
NGC 4250. This galaxy also carries the designation "NGC 4250A". This was
assigned by Philip Keenan in a 1935 paper (ApJ 82, 62) where he listed
"approximate positions" for 32 "previously uncatalogued nebulae". See IC 381
for another previously catalogued example from this paper.
Keenan gave the "previously uncatalogued" galaxies names based on the nearest
NGC galaxy, with suffixes attached to differentiate them from each other.
This is perhaps the earliest use of suffixed NGC numbers, and set a bad
example that others have followed through the years.
Steve's Notes
=====
NGC 4250
17.5" (5/2/92): moderately bright, small, round, broad concentration with overall high surface brightness. The halo appears to extend further on the north side of the core.
