[] Starting observations of the Type Ia SN 2010B

f:id:kanataobslog:20100118204505p:image

We have performed the photometric observations of Type Ia SN 2010B since 2010 Jan.14 UT. SN 2010B was discovered of 14.4 mag at NGC 5370 by Tsuboi, M in Hiroshima (CBET 2115). Thereafter, the spectroscopic observations of this object was performed by Kinugasa, K. et al. reported in CBET 2117. This object was identified as a Type Ia SN before B-band maximum light. Unfortunately, since we obtained the photometric points an week after the maximum, the light curve already show the decline of the luminosity. The decline rate of the B-band light curve seems to be faster than that of a normal SN Ia. We will continue the observations of SN 2010B.

Optical transient in UGC 2773 : update

We update the light curve of the optical transient of UGC 2773.

[] Type II SN 2009md : update

f:id:kanataobslog:20100118194540p:image

We update the light curve of Type IIP SN 2009md.

[] Type II SN 2009ls : update

f:id:kanataobslog:20100118193334p:image

We update the light curve of Type IIP SN 2009ls. The light curve of this object is well corresponding to that of a Type IIP SN. We will continue the observations of SN 2009ls.

[] Type II SN 2009kr : update

f:id:kanataobslog:20100118192637p:image

We update the light curve of Type II SN 2009kr. The luminosity still shows the flat shape of the light curve, which seems to be similar to that of a Type IIP SN.
