                     DR CEPHEI


According to Hoffmeister, Gotz (AN. 281, 182, 1935) and Wenzel (MVS 228, 1956)
DR Cep is an RW Aurigae type variable. The last author published parts of the
light curve showing irregular variations followed by quasi-periodic light
changes exhibiting cycles of about 61 days.

About 130 photographic observations with the Lippert Astrograph showed this
star to be a 19^d cepheid. 17 maxima have been used to derive the following
elements:

Max=2430704.82 +19.^d06588 E
          +-13        +-12

The mean light curve turns out to be very regular without humps. The amplitude
amounts to 1.^m7 and M-m/P=0.28. As far as the graphical representation of the
Sonneberg observations is concerned, given in MVS 228, it looks like there are
no contradictions to the above quoted elements.
