Spectroscopic and photometric study of the bright X-ray cluster A1300

We present the first results of an optical follow-up of X-ray bright clusters of galaxies located between 0.15 less than or equal to z less than or equal to 0.31: B and R photometry as well as medium resolution spectroscopy of the galaxies. The cluster studied here - A1300 - is found to have a redshift of 0.3072 and a velocity dispersion of 1210 km/s, based on 52 cluster members. Structures are observed in the galaxy number counts but the velocity histogramme shows no significant departure from a Gaussian distribution.
