Variable star in Perseus: TCP J04283707+3157578.

KRYCHKO T., SATOVSKI B. and BRIMACOMBE J.

Abstract (from CDS):

Timur Krychko and Boris Satovski report their discovery of a previously unknown variable star (mag 16.9) on unfiltered CCD images (limiting red mag 20.5) obtained on Sept. 22.012 UT using a 0.30-m f/8 reflector at the Astrotel Observatory, Zelenchukskaya Station, in Russia. The variable is located at R.A. = 4:28:37.07, Decl. = +31:57:57.8 (equinox 2000.0 presumed). Nothing is visible at this position on Digitized Sky Survey (DSS) images taken on 1989 Nov. 14 and 1996 Nov. 4, and nothing is visible in 2MASS images obtained on 1999 Nov. 26. However, the object appears visible at mag 17 on Palomar Sky Survey images taken on 1955 Oct. 22 and 1992 Oct. 1. Krychko has posted an image marking the variable at the following website URL: http://www.astroalert.su/files/tcp_04283707_3157578_2011-09-22.jpg.

This variable was designated TCP J04283707+3157578 when it was posted on the Central Bureau's TOCP webpage. Joseph Brimacombe, Cairns, Australia, reports unfiltered CCD mag 19.0 and position end figures 37s.0, 58".1 from an image taken on Sept. 26.426.
