We performed spectroscopic observation of possible supernova in M51 (RA 13:30:05.14, Dec +47:10:11.0). The spectrum exhibits the P-Cyg profile of H-alpha, HeI and CaII IR. The absorption minimum of H-alpha reached 17000 km/s. Those of HeI and CaII did 16000km/s. The spectrum is similar to that of typical Type IIP SN 2006bp at 10 days after its shock breakout. We will continue observations.
We performed spectroscopic observations of Possible nova in Sco on MJD 55714.599 (2011 Jun. 2.599 UT). The spectrum exhibits the broad H-alpha emission line. The line velocity of its FWZI are roughly measured to be 4500 km/s. This emission line shows the triple-peaked profile. The velocity of these peak components are +1600, 0 and -700 km/s, respectively. We also identified the OI 7477, 7773, 8227 and 8446 emission lines. These line profiles exhibit the double-peaked structures. The typical peak separations are estimated to be 2.0nm except for OI 8446. These complex line profiles would be reflected by the overlap of the ejected-material. The HeI lines are not seen in our spectra. We will observe this object.
