Abstract (from CDS):

We present observations of RX J105225.9+571905, a z = 4.45 quasar discovered during a very deep ROSAT survey of the Lockman Hole. In addition to being the most distant known X-ray-selected quasar, RX J105225.9+571905 is among the least optically luminous quasars found to date at redshifts above 4.
