[vsnet-alert 3210] M63 photometric sequence

[bas@lowell.Lowell.Edu (Brian Skiff)]

     Assuming the Messier 63 = NGC 5055 supernova suspect is real (it is
possibly an HII region knot), here is a BV photometric sequence around the
galaxy, arranged in order of decreasing brightness.  The brightest star
is the one superposed on the west side of the galaxy; it was measured by
Harold Corwin.  The fainter stars were measured by me using the Lowell 1.1-m
and published in the Webb Society QJ about five years ago.  These are extracted
from my big file of photometry for faint field stars at:

...although I did add the HD star to the list just now.  The R magnitudes
shown in parentheses (suitable for unfiltered CCDs) were derived from the
V and B-V values.
