We have performed multi-color optical photometric observations of Type Ia Supernova (SN) 2008fv since Oct.2. The light curve exhibits some characteristics of a normal Type Ia SN. The B, V, R-band light curve profile around maximum are typical, and the maximum of I-band light curve precedes than that of other band, which suggested that SN 2008fv is a normal Type Ia SN. The secondary maximum of I-band light curve is seen, while the photometric observation is lacking around secondary. We will continue observation of this object.

[] 3C 66A : light curve & polarization degree

The figure shows the light curve and the polarization degree in V band. The polarization degree seems to correlate with light curve but it doesn't correlate in some days.

We continue the observation of PKS 2155-304. We report the current behavior. The figure shows the light curve and the polarization degree in V band.
