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.
