COMMISSION 27 OF THE I. A. U. INFORMATION BULLETIN ON VARIABLE STARS Number 1912 Konkoly Observatory Budapest 1981 January 19 HU ISSN 0374-0676 POSSIBLE HUBBLE-SANDAGE OBJECTS AMONG VARIABLES DISCOVERED IN THE ANDROMEDA GALAXY With the 2 meter telescope of the Bulgarian Academy of Sciences several plates of the central and south-west region of the Andromeda galaxy have been obtained in 1980. The limiting magnitude is about 21.2 and 22.0 magnitudes for plates of one and three hour exposure time, respectively. Hubble (1929) observed Nova 36 with a constant magnitude of 18.7 during 11 years. (Hubble's magnitude scale is translated into Baade and Swope's (1964) system.) Nova 36 is also visible on our plates: its magnitude is B=20.0. Therefore, our data show that this star is not a nova. Hubble also discovered the irregular variable stars H11, H20, H43 and H44. Baade and Swope observed two of these stars and classified H43 as an irregular variable (20.70m-21.30m) and H44 - as R CrB variable (19.85m-21.45m). H11 and H20, however, have not been. investigated since 1928. Here we give the magnitudes of these stars: J.D. star B(mag) 2444529 H11 21.2 2444529 H20 >21.2 2444530 H43 20.3 2444530 H44 20.0 The magnitudes of H11, H43 and H44 presented above are within the limits of their amplitudes as given by Hubble (1929) and Baade and Swope (1964). But H20 is with about 2m weaker in comparison with its brightness in 1928 (now it is 21.2 in comparison with 18.5-19.5 in 1928). It is quite possible that Nova 36 and H20 are irregular variable stars - Hubble-Sandage objects (S Dor variables). Nova 26 and Nova 39 were also observed by Hubble during several years, but on our plates these stars are not visible (B>22 mag). They are also possible Hubble-Sandage objects. A. S. SHAROV G. R.
