Type II SN 2009js : increasing I-band luminosity in long time scale

f:id:kanataobslog:20091124181330p:image

We upadate the light curve of Type II SN 2009js. Its light curve show the increasing the I-band luminosity in long time scale. Such a plateau in the light curve in long time scale is corresponding to those of Type II plateau supernovae. Slowly rising in the I-band light curve indicates the long time scale of diffusion of the expanding atmosphere with the slowly expanding atmosphere. We will continue the observations of this object.
