DO Dra and QZ Vir
For QZ Vir;
> this star may show an unusual variation,
This shows a rebrightening, for example.
By the way, according to the data obtained Kazuhiro Nakajima, QZ Vir
shows double peak humps on 13th of Jan. This did not appear before the
rapid decline (even 12th of Jan.).
For DO Dra;
> The UGSS type dwarf nova DO Dra is rapidly fading.
I have some additions. First, DO Dra is an intermediate polar.
Next, this star showed a bright minimum before this outburst. Though the
minimum of this star is usually around 15th mag, this star had been around
14.5 mag. from the beginning of 2007 by this outburst occurred.
