f:id:kanataobslog:20090428232607p:image

We have started multicolor photometric observations of Type II SN 2009dd. We showed the light curve in the figure. The muticolor photometry shows that the object is highly reddened by host galactic dust. The light curve of this object seems flat. Such a behavior of the light curve indicated that the similar to that of Type II plateau. If SN 2009dd is Type II plateau supernova, we will conduct a polarimetric observations using HOWPol in order to research a shape of ejecta inner than hydrogen shell.
