\begintext

These stars were discovered and reported to be of RR Lyrae type by Boyce \& Huruhata (1942)
and Hoffmeister (1966, 1967, 1968). 

Except some remarks concerning the type of variability no further
observations or ephemeris have been published until today.

Photographic plates of a field centered at $\alpha$ Oph, taken with the
Sonneberg Observatory 40-cm Astrographs during three intervals spread over
the years from 1964 to 1994, were used to investigate the behaviour of
these objects (see 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 5858-t3.txt}, using the link in
the HTML version of this paper.  Individual data are available upon
request.
