Hello all,
Just a remark -- it would be useful if someone could do astrometry
on an outburst image, so that the quiescent counterpart can be
identified with confidence once the object fades. I may be able
to get some large-telescope images in January to accomplish this.

I was able to observe this object for 2hrs using unfiltered CCD photometry
on a 0.35m SCT before clouds intervened. It showed superhump-like
modulations with an amplitude of 0.2 magnitudes and a period, according to
Peranso, of 0.052+/-0.007days. The mean magnitude was approx 14.85. It
appears to be another UGSU type dwarf nova.

Dear colleagues,
I obtained V and B magnitudes of this object as follows:
object YYYYMMDD(UT) mag code
OT_J055718++683226 20061217.62573 14.95V Mhh.VSOLJ
OT_J055718++683226 20061217.62839 15.11B Mhh.VSOLJ
A USNO B1 star is located close to this object:
USNO-B1.0 1585-0088462 RA=05 57 18.45 Dec=+68 32 26.9 B1=19.04
R1=19.23
A ROSAT X-ray source 1RXS J055722.9+683219 is located at about
0.4 arcmin east from this object.
This object seems to be a new dwarf nova.
Regards,
Hiroyuki Maehara

Dear Wolfgang Kloehr,
I have taken 60 s exposures (in Ic band) with the 14 inch telescope
and confirmed the presence of the object.
As you note, the faint counterpart seems to be present in the DSS2
red.
Regards,
Ken'ichi Torii
