We update optical spectra of V5583 Sgr. Relative Intensities of Emission lines gradually increase. No nebular lines are seen.

[] PSN in UGC 2773

f:id:kanataobslog:20090903231937p:image

We start photometric observations of possible SN in UGC 2773. The new transient was discovered on Aug 18.02 in UGC 2773 (CBET 1931). ).UGC 2773 is a low luminosity galaxy, and its distance modulous is roughly as ~28.5 (from NED). Considering the reddening of Galaxy (Av~1.8 mag), the roughly estimated absolute magnitude is derived as ~-11.9mag. We will continue the observation of this exciting conspicuous object!

[] SN 2009im in S0 galaxy NGC 1355

f:id:kanataobslog:20090903212045p:image

We update the light curve of sub-luminous Type Ia SN 2009im. The brightness

has already finished.

[] SN 2009ig : still before maximum

f:id:kanataobslog:20090903211920p:image

We update the light curve of Type Ia SN 2009ig. The brightness do not still reach maximum light.

[] V2672 Oph : NIR light curve

f:id:kanataobslog:20090903204936p:image

We updated NIR light curve of V2672 Oph.

[] V5583 Sgr : NIR light curves

f:id:kanataobslog:20090903195145p:image

We updated NIR light curves with results obtained on September 1st. The decline trend continues in J and H. No evidence of the dust formation was seen from our light curves.
