EK Draconis: Long-term photometry on Sonneberg Sky-Patrol plates
We performed long-term photometry of the young solar analog EK Draconis(HD 129333) using 1030 blue-sensitive Sky-Patrol plates taken atSonneberg Observatory from 1958 onwards. A secular dimming of 0.0057+/-0.0008 mag/y beginning around 1975 was found. Hence, the recent trendfirst observed with Automatic Photoelectric Telescopes (APTs) isconfirmed and traced back to the mid-seventies.

Mesures de vitesses radiales. VIII. Accompagnement AU sol DU programme d'observation DU satellite HIPPARCOS
We publish 1879 radial velocities of stars distributed in 105 fields of4^{\circ} \times 4^{\circ}. We continue the PPO series \cite[(Fehrenbachet al. 1987;]{Feh87} \cite[Duflot et al. 1990, 1992 and 1995),]{Du90}using the Fehrenbach objective prism method.
