The UoSAT-2 spacecraft, launched in 1984 into a polar orbit of altitude 700 km has a number of systems which have been observed to experience single-event upsets at significant rates. Geographically, the upsets are strongly concentrated in the South-Atlantic Anomaly region from which it has been deduced that in this region they are due to the products of proton-induced nuclear reactions in the devices. During the year 1989, several solar flare events occurred which elevated the upset rates at high latitudes. The October 19 event, in particular, resulted in very high high-latitude upset rates. The authors separate and analyze these data, deriving upset rates for the various memory devices under quiet cosmic-ray, South Atlantic anomaly and solar flare conditions. The authors report on the results of the heavy ion and proton testing of UoSAT memories which were undertaken in order to compare predictions and observations.
