COMMISSION 27 OF THE I. A. U. INFORMATION BULLETIN ON VARIABLE STARS Number 1979 Konkoly Observatory Budapest 1981 June 19 HU ISSN 0374-0676 OBSERVATIONS OF VARIABLE STARS ACCIDENTALLY FOUND ON MINOR PLANET PATROL PLATES While blinking plates for minor planets we have found a few stars obviously changing their brightness. They have mostly been identified as objects listed in the first catalogue of suspected variable stars (Kukarkin et al., 1951). Unless otherwise stated, the observations have been made with the 30cm f:5 astrograph of Hoher List Observatory. 1 ) UW Gem Classified as an eclipsing binary there has been some confusion about its identification (Hoffmeister, 1944). Because no finding chart is available, Fig. 1 shows the variable and its surrounding stars. The brightest objects shown are BD+13d1377 (lower right) and BD+13d1378 (upper middle). The actual observations are JD hel. 2444290.4200 m_pg 17.5m 2444291.4758 15.5 [FIGURE 1] Fig. 1 Finding chart for UW Gem 2) CSV 2361 (Lib) The star has been observed as follows: JD hel.2444369.4857 m_pg 14.5m 2444369.5121 14.5 2444370.5141 15.5 2444371.4884 15.5 3) CSV 3422 (Oph) The first four plates have been taken with the 30cm f:17 refractor of Hoher List Observatory by M.

The variable seems to be faint on the [FIGURE 2] Fig. 2 Finding chart for the suspected variable in Libra Atlas Stellarum by Vehrenberg and on the red print of the Palomar Observatory Sky Survey, but bright on its blue print.
