[dwarf nova] OT J012059.6+325545 : rebrightening

22.png

We detected a rebrightening of OT J012059.6+325545 tonighit (Dec. 28.535UT). In g'-band, the brighteness of the object is about 1.8 mag brighter than that on 2010 Dec. 26. The figure shows our images observed on Dec.26 and Dec.28.

[Dwarf Nova] PT And : a spectrum on 2010 Dec.10

We obtained an optical spectrum of PT And = M31N 2010-12a (c.f. CBET 2574)
according to the report by vsnet-alert on 2010 Deceber 10.
No prominent emission lines were detected in our spectra
as observed in ordinary classical or recurrent novae in its early decline phase.

Our result is in agreement with recent reports that the object
appear to be a dwarf nova  ( [vsnet-alert 12484] , [vsnet-alert 12527]).

[dwarf nova] : OT J012059.6+325545

8.png

We performed simultaneous g'-i' photometry of a new WZ Sge star, OT J012059.6+325545 (vsnet-alert 12431, vsnet-alert 12346 ). The current bright outburst of the object was discovered by K. Itagaki on 30 Nov.(vsnet-alert 12341).

Our preliminary light curves of g'- and i'-band are shown in the figure. The object shows early superhumps with substructures in both bands. These substructures maight be dut to flickerings or eclipses. We continues photometric and spectroscopic observations of this dwarf nova. (A.A)
