COMMISSION 27 OF THE I. A. U. INFORMATION BULLETIN ON VARIABLE STARS Number 2420 Konkoly Observatory Budapest 19 October 1983 HU ISSN 0374-0676 TWO NEW VARIABLE STARS IN THE FIELD OF NGC 6946 Two new variable stars have been discovered on 26 blue plates taken with a 36 cm telescope in a field of one square degree around the galaxy NGC 6946 during the period between July 1964 and September 1966. Figure 1 shows the finding charts:north is at the top,the side is 15'. [FIGURE 1] GR 311.- The position 1950 is R.A. = 20h 29m 47s, D = + 60d10.5'. This star is very likely a semiregular variable. The observations suggest a period of 145 days. A definite maximum has been observed at JD 2439054 (14.9 mph). The photographic range is from 14.9 and < 15.5. GR 312.- The position 1950 of this eclipsing variable (EA) is R.A.- 20h 35m 17s, D = + 59d 57.0'. Two minima have been observed respectively at JD 2438941.423 (15,2) and JD 2438967.436 (<15.3). The period is very likely 26.01/n days. The star has an observed range from 14.5 and < 15.3. In the same field we have observed also the following variables. DT Cep.- Eclipsing variable. Only a minimum at the date JD 2439051.335 (15.0) has been observed. The O-C = -0.143d with the elements given by W. Gotz (VVS 2, n.5, 1956). V778 Cyg.- Slow variations of light between 13.4.and 15.1. Irregular variable. G. ROMANO AND M. PERISSINOTTO Istituto di Astronomia Universita di Padova Italy
