V2135 Ophiuchi and FK Ophiuchi.
Abstract
The variable star V2135 Oph = SVS 2155 = V7 (M19) has been studied on 63 plates of the Moscow collection. The star apparently changed its period around J. D. 2441000; the systems of light elements valid before the period change and after it are presented. Excellent agreement between the values of the period for FK Oph = V2 (M19) derived by Coutts, Sawyer Hogg and by Samus is noted.
