Improved declination for transient X-ray source A0620-00

OBSERVATIONS with the Effelsberg 100-m telescope at a frequency of 4,600 MHz have resulted in an improved declination for the radio source believed to be associated with the transient X-ray source A0620-00 (ref. 1). The observations were made on August 24, 1975 with a cooled parametric amplifier of system temperature 65 K. The bandwidth was 200 MHz, and the half-power beamwidth of the telescope was 2.7′. The measurements were calibrated relative to NGC7027 and 3C286.
