Description:
The famous star cloud in the Great Andromeda Galaxy was very bright
this morning, with a jagged N edge sloping NE-SW; a more irregular
S edge, diffuse especially to the SE, and containing a pronounced
dark "indentation" near the center of the edge. A globular cluster
in M31, known as "G52" in the Luginbuhl & Skiff Observing Handbook,
was readily identified with averted vision to the W. An arcing dark
lane was VERY striking to the E, NE, and especially SE of the star
cloud, where the dark streak was traced through a *degree* of arc-
length, curving S and back NE! Roiling clouds of bright and faint
"nebulosity" stretched S of n206, with 4-5 small, stark dark lanes
bifurcating to the E and W, amid many stellar and more extended
brightenings. Worth every minute spent on this object under such
clear conditions! (See also the log for two nights later, where I
identified several more constituent objects in the great Galaxy!)
