f:id:kanataobslog:20100110183945p:image

We update the light curve of Type II SN 2009js. The light curve would show of the rapid decreasing of the luminosity, which suggest that the recombinations of the hydrogen layer should end. Assuming SN 2009js of a typical Type II SN, the decreasing magnitude is expected to be 5 mag. We will continue the observations of SN 2009js until a limit of a detection by KANATA/HOWPol.
