Description:
Easily found as a brightish "dot" via either 9 Bootis or Beta Comae,
and not many binocular fields from Arcturus, this glorious cluster
was both somewhat larger and about 0.5 magnitudes fainter than M13.
(See M13 "yardstick" observation for this same night). The centers
of both clusters were of similar increased brightness however. But
no hint of a core could be seen in M3.

observations... Please discard this and following if not.]
