V1280 Sco : finished rebrightening

We performed observations of V1280 Sco on 13,14 and 26 January 2008 
in optical and near-infrared bands. Our photometric results 
clearly indicate that a rebrightening trend finished 
and color became blue. The rebrightening continues since July 2007, 
we confirmed that the trend lasted until 23 October 2007.

KANATA observation on 2008 January 26.895023 UT
Rc=10.3,  Rc-Ks ~ 5.6

Our results indicates that the optically thin dust shell still exist 
around the system, because the Ks-band flux of V1280 Sco is still brighte.
