             THE FLARE STAR UV Cet

      Members of the Variable Star Section, Royal Astronomical
Society of New Zealand, monitored UV Ceti during the
international observing session 1968 Oct. 14 to 28 for
a total of 27 1/2 hours. All observations were visual except
1968 Oct. 27 1049.4 to 1314.1 when F. Andrews and Mrs. A.
Andrews monitored UV Ceti with the photoelectric photometer
at the West Melton Observatory attached to the 40cm reflector,
using a B filter. This period coincided with very poor
seeing throughout N.Z. with the result that such brightenings
as were recorded visually do not exceed the errors of
observation under the sky conditions prevailing. Three
suspected flares were recorded photoelectrically and are
listed below but are considered of low reliability because
of the observing conditions at the time. A summary of the
hours of coverage is given below.
