            A NOTEWORTHY STAR IN SERPENS




    In the course of a search for galaxies with ultraviolet
continuum on plates obtained at Byurakan 40" Schmidt-camera with
a low-dispersion objective prism survey, we have discovered a
new variable star whose brightness in comparison to POSS was
about four magnitudes brighter corresponding thus to m_V= 14m.
    On slit spectra (D=200 A/mm) taken with the Byurakan 2.6 m
telescope on June 6, 1978 we discovered the following very strong
and broad emission lines: HeII 4686, HeI 6678" 5875, 4471, 3888,
H_alpha-H_epsilon. There are no forbidden or absorption lines, and it is 
necessary to note that all emission lines are broad. The total
width of H_alpha line on the continuous spectrum level is about 70A,
which corresponds to an expansion velocity of more than 3000 km/sec.
We obtained only one spectrum in red and one spectrum in blue
regions.
    Using the plates of several co-workers of Byurakan Observatory 
we followed the behaviour of the star from May 1965 and
established that the star's brightness in the period from May
1965 to May 1979 was about m_V =14m.       
    We do not have any data in the period from April 1950 (POSS)
to May 1965, so that it is not possible to establish when and
how the brightening took place.
    From its flare amplitude, long time sojourn on this higher 
level of brightness and the presence of only wide permitted lines,
we have not succeeded to adhere this star to any class of flare
stars.
    Identification chart in red colour reproduced from POSS and
coordinates for the epoch 1950 are given below. North is at the
top, east is to the left. The field is approximately 16'x 16'.       

           RA = 15h35m44s       Decl. = +19d01'30"
