       LIGHT CURVE OF THE EMISSION VARIABLE IN SAGITTA

The emission object announced by O.D. Dokuchaeva in IAU
Circ. 2995 and IBVS 1189 was observed on Sonneberg field and 
patrol plates mainly taken by R. Brandt and H. Huth. The variable
was invisible (fainter than 15m to 16m) on roughly 250 blue 
sensitive plates of the 14 cm lenses in the years 1930 to 1969 and
invisible (fainter than 13.2m pg or 12.5m pv) on blue and photovisual 
material of the sky patrol from 1970 to 1974 Dec. 13.
   The outburst of 1975/76 as observed in photovisual (x)
and blue light (.) is shown in the Figure. The object's red colour 
which obviously also belonged to the minimum (see Palomar
charts), was strongly present at the ascending branch, smaller
during maximum and no longer conspicuous in 1976. The systematic
difference between the Harvard data (IAU Circ. 3005) and ours
has still to be explained.
   The comparison stars were tied to SA88 (Mt. Wilson system)
for m_pg and to our sequence near WW Vul (Astron. Nachr. 294, p. 29)
for m_pv. They can be identified on the map in IBVS 1189 with respect 
to the variable star, as follows:
