[] V1280 Sco : The light curve

f:id:kanataobslog:20090401235101p:image

V1280 Sco is a classical nova which formed dust shell in the early phase of its eruption. The optical flux have recovered since autumn 2007 from V~17 to 11 due to the termination of the dust condensation. After the recovery, fluxes in V and J gradually increased for a year. Our recent V- and J-band light curves show that the brightness of the nova slightly decrease. This might indicate that the oncet of the "final decline" of V1280 Sco due to stop of the Hydrogen burning on the white dwarf.
