Περίληψη:
In 2005 a photometric observation campaign started on the open cluster
chi Persei, involving 13 telescopes spread over the whole northern
hemisphere. After two years we gathered almost 1200 hours of data. We
present here preliminary results on the variability search, especially
from the 60-cm telescope in Bialkow (Poland), which show seven confirmed
beta Cephei stars, four candidate B-type pulsators and other interesting
variable stars.
