MisV1443 (= MPRE 2011-0001 = OT_J062000.0+192659): new WZ Sge-type dwarf nova
(The latter identification can be used)
Enrique de Miguel has just reported observations as below:
Possible new object detected in the MISAO project
(VSNet alert 12580). Detected at mag 14.3C on Jan 8.
After a ~4.2-hour time series, this object exhibits
sort of double-hump oscillations, with full amplitude
~0.08 mags. An ANOVA analysis detects a well-defined
periodic signal at 0.0593(29)d. This object could be
a DN but no definite conclusion can be obtained from
this single run.
The present variation is most likely early superhumps of a WZ Sge-type
dwarf nova. An analysis has yielded a period of 0.0599(4) d, but we expect
it that will soon be improved by further observations!
