In AN 281, p. 179 WENZEL previously reported on the irregular variations of
this star. In the meantime I observed it on further plates. These observations
have shown that the object probably belongs to the group of "nova-like"
variables in a wider sense. During the time of observation the brightness of
the star underwent 5 maxima, separation 2000 to 4000 days, height roughly
0.^m7 (see figure).


                          [FIGURE 1]
                       

The colour of the star is not remarkable. On an objectiv prism plate of the
Sonneberg Schmidt camera the spectrum is much disturbed by a neighbouring one.
It does not show emission lines and seems to be of medium or early spectral
type; no further conclusions can be drawn. Spectroscopic observations of the
variable are therefore of special interest.

The magnitude scale at the figure has been taken from WENZEL (l.c.).
