[vsnet-chat 1513] AC Cas field

[aah@nofs.navy.mil]

The Bengtsson variable candidate near AC Cas is red, but there
are many red stars in this field (probably some reddening in
the region), and therefore its color may not be intrinsic.
AC Cas, on the other hand, is the reddest object
in the field.  Since my observations were spaced two nights apart,
I would not expect much variation from a semi-regular variable
like AC Cas (which is why I'll look at the field again in a month).

There is another star which deserves attention:

   RA          DEC         V      err   B-V   err
15.93647957  71.96189880 13.514  0.793  0.988 0.953

It lies very close to a 11.7mag star, and probably is just contaminated
by that neighbor (especially since seeing was so poor this observing
run), but it may be an intrinsic variable.  I'll know more next month.
