摘要：
We present Vela 5B observations of the Small Magellanic Cloud region obtained during the years 1969-1979. We detect the 3.89 day orbital modulation of SMC X-1 with a false alarm probability of 4.3 x 10(-3) and observe a ''high state'' beginning in 1970 September and lasting similar to 100 days. We also detect three outbursts by a transient source consistent with the position of the candidate Be-neutron star system H0107-750 (=1H 0103-762). These events occur roughly 100 days apart and last for similar to 35 days. No detections of SMC X-2 or SMC X-3 are apparent above a limit of similar to 7 x 10(37) ergs s(-1).
