DV UMa: eclipses on April 9
The Kyoto team has succeeded in obtaining the light curves of
three eclipses of DV UMa on April 9. There is no superhump in
this light curve. The eclipses apparently have two components,
one is presumably of a disk and the other is probably of a white
dwarf or a very bright region in an inner accretion disk:
the object must have been in a very early phase of superoutburst
at that time. The superoutburst is still ongoing. More
time-series observations are encouraged. The weather was bad
for these days in Kyoto, but we will be able to restart observations
tonight.
Regards,
Makoto Uemura
