MisV1448     Profile MisV1448 R.A. 19h59m19s.44 Decl. +56o25'20".7 (2000.0) Mag. 13.3-[16.6C Type UG: = USNO-A2.0 1425.10173307 19h59m19s.449 +56o25'21".10 Mag(R):16.8 M ag(B):17.7 Digitized Sky Survey GIF image (15 x 15 arcmin) SIMBAD Query AAVSO VSX Database ASAS-3 Light Curve Discovery Information Seiichi Yoshida, Yokohama City, Kanagawa, Japan; discovered a new object from survey images taken by Youichirou Nakashima, Setouchi City, Okayama, Japan; in the course of the MISAO Project. It was bright at 13.4 mag on May 27, but nothing found in our past images. We found a 17-mag star, USNO-A2.0 1425.10173307, in the USNO-A2.0 catalog at this position. So it seems to be an outburst of this 17-mag star. We the MISAO Project assign the new variable star number "MisV1448" to this star. Denis Denisenko reported the pre-discovery data by the MASTER robotic telescopes, and confirmed the outburst of this star. It has brightened up to 12 mag on May 13. Special Notes New bright dwarf nova discovered at 13.4 mag from 2012 May 27 images. Seiichi Yoshida discovered this object on June 8, about 2 weeks have already passed. However, Denis Denisenko found the pre-discovery data by the MASTER robotic telescopes at 12 mag on May 13, and confirmed the outburst of this star.
