[] Spectroscopic Observations of Type Ia SN 2008fv

f:id:kanataobslog:20081205015001p:image

We have performed spectroscopic observations of bright Type Ia SN 2008fv since Oct. 2. We obtained 9 specra. The broad and deep SiII6355 line was seen at 6100A in our spectra until Oct.20. The CaII IR triplet line also showed strong blue-shifts at 8200A. The both lines indicate that SN 2008fv is a normal Type Ia supernova. The observations will continue.

[] PKS 0422+004 : correlation between light curve and polarization degree??

f:id:kanataobslog:20081204223511p:image

The figure shows the light curve and the polarization degree of the object in V band. The polarization degree seems to correlate with light curve.
