■ [Extragalactic nova] M33 2010-07a : rebrightening ?
We update the light curve of extragalactic nova M33 2010-07a. The light curves of I and R-bands show the sudden rebrightening. The rebrightening just after the maximum light is also seen in that of Galactic very fast nova V2498 Cyg. Such a phenomena may be caused by the strong magnetic filed of the surface of the white dwarf. We will continue the photometric observations of M33 2010-07a.
