Description:
While the "middle child" of a pretty, wide-field trio of galaxies with M60 and
n4647 (see previous logs this night), M59 is much the least interesting of the
group. Tonight, its diffuse halo appeared slightly elongated N-S about 4' long,
with a still barely elongated inner halo about 2.5'x2', bearing a symmetrically
centered brighter core perhaps 1' around inside, and no hint of a nucleus. Its
interest is very much enhanced in a low-power field by the pretty right triangle
it makes with its neighbor galaxies. (See following log for NGC 4638.)
