35.jpg

We update our light curves of OT J012059.6+325545. Our latest observations were performed on Jan. 19. The object showed a rapid and deep fading between Jan. 17 and 18. But, a large rebrightening was observed again on Jan. 19. A large spike was also observed at the last part of its rebrightening phase of WZ Sge in 2001 outburst (ref. Ishioka et al. 2002 and http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/DNe/wzsge.html). We specurate that this large rebrightening of OT J01205+325545 may be also the last rebrightening of the current rebrightening phase, because the rebrightening phase of OT J01205.6+325545 is very similar to that of WZ Sge.
