[vsnet-alert 1107] possible outburst of RY Ser

[Taichi Kato <tkato>]

Dear Colleagues,

    While examining CCD images taken at Ouda Station on August 2, I noticed
the obscure dwarf nova RY Ser seems to be in outburst.  The star was
possibly misidentified in Downes et al. (1997, PASP 109, 734).  The star
south to the marked on Downes's atlas is substantially brighter than their
image.  The suspected object is located at

    17h 23m 07s.17   (J2000.0)
    -12o 48' 09".1

and was estimated as V=14.5.  This identification seems to be supported
using a chart by A. M. Chernenko (Perem. Zvezdy Suppl. 20, 265, 1982),
though its hand-written feature has made the comparison rather difficult.

    Could someone please check this field to see which star is actually
RY Ser?  Downes's object was also observed at V=15.5.  A more detailed
information with a VSNET chart will follow later in vsnet-obs.

Regards,
Taichi Kato
