f:id:kanataobslog:20110122211957p:image

We update the data of 3C 66A. The figure shows the light curve in the V band and V-J color variation of the object. The object have been gradually brightened superimposed the short timescale flares which typical timescale is several days since JD 2454810. Although there is the short timescale variation, the V-J color was around 1.7.
