Abstract

REDSHIFTS of between 2.5 and 3.1 have been measured for nine optically-selected quasars as part of the Cerro Tololo survey of the Southern Hemisphere (M. G. Smith, see ref. 1). None of these quasars were known to be radio sources. We chose several accessible quasars from Smith's list as a starting point in our investigation to see if they might not be radio sources. We report that Q0000–398 is a quasar of high redshift and large angular size.
