  Title: OBSERVATION OF HIGH REDSHIFT, HIGH X-RAY LUMINOSITY CLUSTER RXJ1449.5+0801      


Abstract:
 >From from CCD imaging of ROSAT All-Sky survey sources without a clear optical
 counterpart, we have identified a cluster at a redshift of 0.65. This cluster is the
 most luminous cluster known above a redshift of 0.5. This cluster is the best
 available candidate for constraining the iron abundance in the ICM at large
 look-back times due to its high X-ray flux. This cluster is the subject of follow-up
 ROSAT, S-Z, radio and gravitational lensing observations.
