Abstract
WE report on some bursts of hard X rays seen in March 1976 by the Ariel-V scintillation telescope (ST). The timescale of a few seconds, the correlation with low energy events seen by a proportional counter on the same satellite (ref. 1 and S. J. Bell-Burnell, private communication) and a photon energy > 50 keV, are factors which suggest a connection in origin between the gamma bursts of Klebesadel et al.2 and the X-ray events noticed by Grindlay et al.3. A delayed arrival at high energies seems to be an important feature of our observations.
