DV UMa eclipse and superhumps (update)
(cf. vsnet-alert 3796, 3801, 3803)
Preliminary analysis of the Dec. 10 observations ay Kyoto (M. Uemura
and T. Kato) shows a remarkable growth of eclipses. In contrast to
shallow (0.9 mag) eclipses, we observed deep (up to 1.6 mag) eclipses
as were observed during the 1997 superoutburst. The observation, together
with Novak's most important coverage of the rising stage (Dec. 8), clearly
demonstrates the quick evolution of the accretion disk during the early
stage of the rare superoutburst in this interesting SU UMa-type dwarf nova.
More information and the new superhump period will be issued later by
Uemura-san.
Regards,
Taichi Kato, Makoto Uemura, Rudolf Novak
