We update optical spectra of V5583 Sgr. Relative Intensities of Emission lines gradually increase. No nebular lines are seen.
■ [Possible supernova] PSN in UGC 2773
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!
We update the light curve of sub-luminous Type Ia SN 2009im. The brightness
has already finished.
We update the light curve of Type Ia SN 2009ig. The brightness do not still reach maximum light.
