■ [Extragalactic nova] M33 2010-07a : rebrightening again !
We update the light curve of M33 2010-07a. The light curve exhibit the rebrightening again. The light curves show the fast decline rate just after the maximum date. Thus, this nova may undergo the very rapid evolution of expanding atmosphere and have already progressed in the transitional phase. Alternatively, the dust formations in the nova ejecta might result in rapid decrease of the luminosity and the rebrightening.
