Abstract
DURING a continuing program of radio observations of X-ray sources carried out with the NRAO very large array (VLA), we have made high sensitivity searches for radio emission from MXB1837 + 05 = Ser X − 1 (ref. 1), particularly during the SAS 3 MIT world-wide X-ray burster watch in June 19772. Observations of MXB1837 + 05 were carried out on 26 April, 12 and 13 June 1977, with six 25-m antennas of the VLA operated at 4,884 MHz with system temperatures of ∼60 K and bandwidths of 50 MHz. Upper limits of 1 mJy were obtained for the time-averaged radio emission from Ser X − 1 during the three periods of observation, and no short time scale radio emission was detected during or after the times X-ray bursts were observed on 12 and 13 June 1977.
