The recurrent X-ray transient A 0538 - 66

Abstract
Ariel V observed two X-ray outbursts from the LMC in 1977 June and July: the events were separated by 17 days and each lasted several hours. The data are consistent with both outbursts being due to a previously unreported transient source that we designate A 0538 – 66. No evidence was found for regular pulsations. A spectrum obtained near the peak of activity was best represented by a thermal plus Gaunt model with a temperature of 6.5 keV and a 2σ upper limit to a low-energy turnover of 2 × 1022 hydrogen atom cm−2. If this source is in the LMC then the peak flux represents a luminosity of 8.5 × 1038 erg/s.
