Discovery Information
We discovered a possible new object from Youichirou Nakashima's survey images in the course of the MISAO Project.
I checked the Minor Planet Checker, the SIMBAD database and 2MASS images, and found nothing at this position.
Today we in Japan are cloudy and cannot confirm this object.
I also reported this to VSNET-alert mailing list.
Further information about this object:
Discoverers: Seiichi Yoshida, Yokohama City, Kanagawa, Japan; and Youichirou Nakashima, Setouchi City, Okayama, Japan
Yoshida discovered this object from Nakashima's images, in the course of the MISAO Project.
The limiting magnitude of discovery images is 16.2 mag.
In the DSS images, a faint blue star is found at this position.
Ken-ichi Kadota found USNO-B1.0 1094-0104214, R.A. 06h19m59s.9113, Decl. +19o26'59".210, 20.480 mag(B1), 20.390 mag(B2), at this position.
Additional information about the DSS images.
A faint star is visible at this position on the DSS blue image on 1996 Feb. 14, 03:42 (UT). But only a hint of this object, nearly noise level, is visible on the DSS red image on 1996 Oct. 9, 11:00 (UT). Nothing is visible on the DSS infrared image on 1994 Nov. 27, 08:23 (UT).
Special Notes
New bright dwarf nova discovered at 14 mag from 2011 Jan. 8 images. It was bright as 12.8 mag already on Jan. 2 in the Stanislav Korotkiy and Kirill Sokolovsky's images. It revealed that the MISAO Project discovered this object about one week after the explosion, and the object has already faded by about 2 mag.
Spectrum observations by Plaskett telescope and Akira Arai confirmed it to be a dwarf nova in outburst. Ken-ichi Kadota and Brian Skiff revealed that the progenitor before explosion is a 20.5-mag blue star.
Adolfo San Segundo detected the re-brightening up to 15.32 mag on Feb. 3, 2011.
This dwarf nova was announced in CBET 2633.
