Abstract
FIVE large outbursts of radio emission from Cygnus X-3 have been reported, (refs 1–3 and V. A. Hughes, unpublished). We present here observations of a sixth, which occurred in June and July 1973. The observations were made using the 46-m telescope of the Algonquin Radio Observatory at 10.6 GHz (bandwidth ∼100 MHz, system temperature ∼120 K). A total of 60 flux density measurements, each providing 7 min of integration time on the source, were made during the period June 25 to July 6, 1973. These observations were taken at sporadic intervals during our programme of measuring early-type emission-line stars, and the observing technique described in ref. 4 was used.
