2011CBET.2633....1Y

Seiichi Yoshida, Yokohama, Kanagawa, Japan, reports that he found a new variable star (mag 14.3-14.4) on CCD images (limiting mag 16.2) taken by Youichirou Nakashima (Setouchi, Okayama, Japan) on Jan. 8.597 UT in the course of the MISAO Project with a 0.25-m f/4.2 Wright-Schmidt reflector (+ SBIG ST-1001E camera). The new object, which was posted on the Central Bureau's new "Transient Objects Confirmation Page" with provisional designation TCP J06195996+1926590, is located at R.A. = 6:19:59.96, Decl. = +19:26:59.0 (equinox 2000.0). Nothing is visible at this position on unfiltered CCD images taken by Nakashima on 2010 Nov. 29.77 (limiting mag 16.3-16.4) or by Nobuo Ohkura on 2000 Feb. 27 (0.16-m f/3.8 Wright-Schmidt reflector + SBIG ST-8 ABG camera; limiting mag 16.1), and nothing is present on a Digitized Sky Survey (DSS) infrared image from 1994 Nov. 27; however, a faint star is visible at this position on the DSS blue image from 1996 Feb. 14.15 UT, and a hint of this object maybe be present on a DSS red image from 1996 Oct. 9. Yoshida has posted Nov. 29 and Jan. 8 images at the following website URL: http://www.aerith.net/pub/MPRE2011-0001.jpg. Yoshida forwards the following magnitudes for the variable obtained by Nick James (Chelmsford, U.K.) on Jan. 9.800: V = 14.38, R_c = 14.36, I_c = 14.53. Yoshida adds that Ken-ichi Kadota found that a star in the USNO-B1.0 catalogue (blue mag 20.4-20.5) has position end figures 59s.9113, 59".210. Yoshida also notes that Brian Skiff (Lowell Observatory) finds the variable to be only 0".1 from the the GSC-2.3-catalogue position for the blue star, which has position end figures 59s.93, 58".8 (from a IIIa-J plate at epoch 1996.112); a SuperCOSMOS scan of the same plate shows the identical coordinates and blue magnitude 20.56.
