\noindent{
These stars were reported to be variable by 
Hoffmeister (1949, 1966, 1967, 1968) and Boyce and Huruhata (1942).
Except in the cases of V946 Oph and V2202 Oph (see details noted in the remarks below), no further observations or ephemeris have been published until today.
Photographic plates of a field centered at 67 Oph, 
taken with the Sonneberg Observatory 40cm Astrographs during three intervals spread 
over the years from 1938 to 1994,
were used to investigate the behaviour of these objects (see \mbox{Table 1}).

The given elements were obtained by means of least-squares solutions.
Photographic amplitudes were derived with respect to magnitudes of the 
comparison stars given in Table 2. An extensive list holding the times of maxima derived can be retrieved as {\tt 5703-t3.txt}, using the link in the HTML version of this paper. 
Individual data are available upon request.}

{\em Remarks:}
\vskip 1mm
{\em V946 Oph}

The period previously published by of G\"{o}tz et al. (1957) and cited in the 
GCVS is erroneous. The brightest maxima published by G\"{o}tz et al.
were included in our period analysis.
\vskip 1mm

{\em V2202 Oph}

The brightest observation published in the paper of Hoffmann (1981) was included in the period analysis.
