Dear colleagues,
Following a request from T. Vanmunster and T. Kato, I would like to
report on the superoutburst in CI UMa in Jan., 1995. This outburst
was first found by J. Pietz on Jan. 8.091 (vsnet-obs 12), and we started
the time resolved CCD photometry on Jan. 8 at Ouda Station using 0.6m
reflector. CI UMa have reached 13.8 mag.
Superhumps have already grown to the amplitude of 0.21 mag. and we
could catch four clear superhump maxima during the 6 hours photometry
on the first day. The best estimated superhump period is 0.0626
(+- 0.0005) day (see vsnet-alert 1). After that, the secular decline
(0.14 mag/day) continued. On Jan. 16, the rapid decline started and
the superoutburst came to an end.
Best regards,
Daisaku Nogami
