DY PERSEI
Professional Astronomers in Latvia have asked us to monitor DY Per
(located RA 02h31.7m DEC +55 56 [1950]) which they believe may be
of R-CrB type. Their research shows the range as 10.4-15.4V. The
star was incorrectly referred to as FY Persei in E605.

A (b) chart with 438 stars and additional bright comparisons is
available via the data file var.log which comes with updates of
the FINDERS.EXE program. Alternatively paper versions of (b) and
(c) will shortly be sent to GOLD e-subscribers who have also
requested paper charts under category 9.
