Abstract
A rocket-borne measurement carried out on March 3, 1969 has yielded a net (dead-time-corrected) exposure of 104 cm2 sec to the differential spectrum of X-radiation from Sco X-1. The data are fully consistent with radiation from an optically thin thermal source, even to the extent that K-emission from high ionization states of iron appears to be present. Such iron emission is consistent with cosmic abundance at the measured temperature.
