We update the light curve of peculiar Type Ia SN 2009dc.

[] PKS 1510-089 : Rebrightening

f:id:kanataobslog:20090508000907p:image

The figure shows the light curve and the temporal variation of the Polarization degree the object in V band. The object had a flare from JD 2454900 to 2454940. Recently, the object has a rebrightening, and at the same time, the polarization degree becomes high. This behavior is similar to the prior flare.

[] PKS 1502+106 : Bright

f:id:kanataobslog:20090507175454p:image

The object was in the brightest state in our observing period. The object has been bright since JD 2454945. The polarization degree was also high compared with that in JD 2454940.

[] OJ 287 : fading

f:id:kanataobslog:20090507175102p:image

The object has been faded since JD 2454940. The brightness reached V~15.6. The color variation has become bluer compared with the color around JD 2454900.

[] J1509-21: return to the quiescent state
