     ON THE VARIABLE STARS IN FIELD OF M2


The three variable stars discovered by R. Margoni and R. Stagni in the field
of the globular cluster M2=NGC 7089 (IBVS 239, 1967 Dec. 9) were estimated on
64 Moscow plates (J.D. 2437078-277). All three variables belong to the
RRc-type with the following elements:

            NEW VARIABLE WITH SYMBIOTIC SPECTRUM


One of the variable stars discovered in VSF 193 in Sagittarius is the
symbiotic-spectrum star, MH_alpha 208-51, or No. 313 in the Merrill-Burwell
(Astrophys. J., 112, 72, 1950) list of stars whose spectra show H_alpha in
emission:

Position (1900)              Max    Min
18^h 31^m 59^s -22d 46.'7   14.0   15.3   Sp. M6e
Primary Min.=2429850+850^d

The light curve and period closely resemble those of CI Cygni, with long
duration of maximum and comparatively short minima (cf, Aller, L.H. Pub. Dom.
Astrophys. Obs., 9, 321, 1953). In CI Cyg two almost nova-like outbursts have
been observed, one by N. Greenstein (Bull. Harvard Coll. Obs. No. 906,
1937) on Harvard plates of 1911, and another in May, 1937, on plates of the
Maria Mitchell Observatory (AAVSO Abstracts, October 1966). No such outbursts
have been found for MH_alpha 208-51. Both stars merit extensive observation.
