During a 54 hour balloon flight from Alice Springs, Australia, on 1978 November 22-24, the X-ray binary 4U 1700-37/HD 153919 was observed in the energy range 20-180 keV for about 2 hours on each of three consecutive days. During one observation when the source was in binary eclipse, no X-rays were detected from the source region. In the other observations flare-type variability was found up to a factor of 25 on time scales of minutes to hours. The source shows a thermal bremsstrahlung spectrum with a temperature kT equals 28 keV, which does not change significantly during the outbursts. This behavior is discussed in terms of current models for the accretion onto nonmagnetic neutron stars.
