Remark:
In 1891 - 1964 light variations in the range 14.2m - 15.5m
with deep minima to 18m; the minima are satisfied by the
elements given in the Table; D = 0.1p; spectral type M
[07235]. In 1964 - the outburst up to 12.1m. Then gradual
brightness decrease superimposed by periodical
variations with an amplitude near 1m. Light minima
as before are satisfied by the elements given in the
Table but the character of eclipses changed (probably
because of appearance of a dense envelope ejected
by one of the components of the system). After the
outburst high excitation emission spectrum with IR
excess is observed similar to the spectrum of symbiotic
variables.
