The depth of Min I varies from 0.2m to 0.9m V,
the depth of Min II varies from 0 to 0.4m V. Two
systems of H, HeI, HeII emission lines are ob -
served in the spectrum: the "stationary" sys -

150 km/s with P = 13.1d, and the "relativistic"
one, corresponding to Vr changes from +50000
to - 35000 km/s with P = 165.5d. The spectral
study [0535]. The system apparently consists
of an O - B star filling its inner roche lobe
and a compact object surrounded by an accre-
tion disc wich is precessing with P = 165.5d.
Two jets consisting of dense condensations of
matter emerge from the system with relativistic
velocity (0.27 c) in opposite directions. The
luminosity of the disc amounts to not less
than 60% of the total luminosity of the system
[0926, 0953]. The object may be a former su -

and dust surrounding the hot companion. The
brightness has physical fluctuations with the amp-
litude up to 0.24m and the cycle about 110d [2040]

star surrounded by an accretion disk. Usually fla-

brightness increased from 16.0m to 11.2m B. In 1967 -
69 the brightness steadily increased to 10.05m B,
being constant in V system (10.5m). In the infrared it
changes in the limits 6.9 - 8.4 J, 4.7 - 5.8 K with the

nebula (NGC 7000). In 1969 - 70 (JD2440400 - 830)
the outburst from 16.5m to 10.3m occured. Brightness
maximum was observed at JD2440830 (spectrum-
B3). Before the outburst the light changed in the range
15.5m - 16.5m, the spectral type was Ke with characte-
ristic features of T Tau type stars [2698, 6415]. Af-
ter the outburst the brightness began to weaken mo-
notonouosly and in 1982 reached 13.1m B (the spect-
ral type about G2 - G5 Ib). Strong H alfa emission appea-
red in 1971. There are also small rapid light fluctua-
tions. Description of light variations [6504, 7115,
7754, 8996]. The star is associated with a luminous
arc-shaped reflection nebula. This nebula with length
of about 3' appeared in 1971 and its brightness is
gradually decreasing simultaneously with the fading
of the star.

as before are satisfied by the elements given in the

of light, the brightness of the Nova gradually increased
from 17.6m to 13.5m B (JD2442632 - 653.2). After Max
almost monotonous decay of brightness is superimpo -
sed by light variations with the amplitude of 0.03m -

JD2442656 - 43100 changed in the range 0.1415d [9167,

CRL 2688, the star of the spectral type F5Ia, associa -

to the north from the source. Since 1920 to 1958 the
integrated light of this component increased from 15.2m
to 13.4b B and after that does not vary [8735]. Light
of the faint (16.2m B) southern component (5" to the

radiation of the nebula is strongly polarized (46%,
teta = 106deg in V system). There are C3 absorption fea-

The Table gives elements for light minima due
to eclipsing variability and the reflection effect. Min I
coincides with the X-ray eclipse. Shallow Min II may
be present. The reflection effect causes variations
with delta(m) up to 1.5m. A cycle of 34.875d duration is
observed in X-ray band; the source is faint during
two thirds of the cycle. The optical light curve chan-
ges are observed during the 35d cycle [9283]. Ac-
cording to [6539], during JD2427543 - 657 and JD
2428630 - 29789 the strong reflection effect was ab-
sent; the star was still varying with P = 1.7d and had
delta(m) ~ 0.5m, Min I = Min II. In [6546] it is stated that
such intervals with no reflection effect, of 8d to 7a
duration, took place for almost half the time since
1890. The light changes during such intervals are in
the range 14.7m - 15.2m pg. Since 1957 intervals wit -
hout the reflection effect were not observed. In June -
July 1983 the predicted phases of high X-ray flux
did not take place, but the reflection effect did not
disappear [9284]. Secondary light variations: P1 =

By the character of
light variation and the spectrum the star is unique.
The light curve resembling those of RCB type stars
is superimposed by conspicuons irregular and semire-
gular variations with the mean cycle about 200d
[2449, 9824]. The star is surrounded by a nebula the
radius of which equals 1". A fainter nebulous envelo-
pe is observed up to 7" from the star. Large infrared
excess. Spectrum description [2451, 9825]. Probably
the star is intermediate between the RCB variables
And planetary nebula Wolf-Rayet central stars.
V350 Sgr SB [9004].
