MULTISITE CCD PHOTOMETRY OF DELTA-SCUTI STARS IN THE OPEN CLUSTER NGC-6134 (THE FIRST STACC CAMPAIGN)

The results of a two-site observing campaign of the open cluster NGC 6 134 are presented. The observations mainly consist of time series diff erential CCD photometry with a Johnson V-filter over a period of 10 da ys. Six, maybe seven, delta Scuti stars are present in the cluster. Mo des have been identified in six stars, and up to 5 modes have been fou nd in a single star. No secure mode identification can be made yet due to lack of sufficient data for the stars, but some ideas about the na ture of the modes can be obtained by utilizing the fact that all the v ariables belong to the same open cluster.
