O článku:
We present the UBV(RI)C photometry of a new dwarf nova
V466 And, discovered during its superoutburst on Sept. 1.6, 2008 and
classified as a WZ Sge-type object. In the first 11 days of the
superoutburst, the early superhumps with the period of 0.056383d
were found. In days 13 — 23 of the superoutburst, the ordinary superhumps
with the period of 0.05713d were exposed. They were replaced by
late superhumps with the period of 0.056d in days 24 — 33 of
the superoutburst. After one month, the dwarf nova returned to its
pre-outburst state. A list of known WZ Sge-type dwarf novae,
including suspected ones, is presented. We determined a mean value of
superhump period excess for WZ Sge-type objects as
ε=0.019±0.003. The multicolour photometry of the
field stars enables us to conclude that there is no appreciable
interstellar extinction in the direction of V466 And.
