NSV 12872
Mike Collins, Everton, UK reports his discovery of a variable star
on exposures of 1992 Apr 5.1UT for the UK Nova/Supernova Patrol.
The position is: RA 20h 09.6m DEC +66 48' [1950], placing the
object in area 5 (Draco). At discovery the mpv (135mm FL + Kodak
2415) was 11.2.
With the assistance of the Royal Astronomical Society, a fax was
obtained of a paper by Morgenroth which showed the object was
identical to NSV 12872 discovered in 1934 with a catalogued
photographic range of 14.5-[15.5. The star was not visible on: the
master shot in Mike's collection of slides, TVMPSA or Atlas
Stellarum.
Subsequently Mike Collins has found earlier images and has derived
the following light ephemeris:
JDmax = 2447660 + 266E.
The star is catalogued in the GSC as:
GSC 4244.00152 with V=11.22.
We do not at present have the type or spectral class. However a
prime focus photograph of the star would be very useful.
The following e-chart has been prepared by Mike Collins:

R SCUTI
Professional astronomers at Keele have asked if we could report
observations on a weekly basis of R Scuti as they wish to
correlate these with their own studies in the ultraviolet. They
have forthcoming shifts with the IUE satellite and the pattern
of observations leading up to these runs would be valuable.
Please e-mail your results weekly to the Editor.
