[] QSO 0133+476 (MIsV1436) ; high polarization degree

f:id:kanataobslog:20090903051533p:image

We update the data of the object. The polarization degree was as high as 33 % in V band.

[] SN 2009im : after maximum

f:id:kanataobslog:20090902203923p:image

We update the light curve of Type Ia SN 2009im. We showed that the brightness reached around the peak. This object would be sub-luminous event (Ayani et al. 2009, CBET 1934). .

[] SN 2009ig : maximum will come soon

f:id:kanataobslog:20090902202012p:image

We update the light curve of Type Ia SN 2009ig. SN 2009ig would be spectroscopically classified as over-luminous SN 1991T-like (private communication from Kinugasa). The absolute luminosity is roughly consistent with such a spectroscopic result.
