■ [Extragalactic nova] M33 2010-07a : slow decline after the rebrightening
We performed the photometric observation of M33 2010-07a. This nova underwent the rebrightening just after the rapid decline. This phenomena is also seen in that of V2491 Cyg (Arai et al.). The timescale of its decline of M33 2010a-07a may be also similar to that of V2491 Cyg.
