Ariel V Sky Survey: long-term monitoring of the X-ray emission from the Coma Cluster and NGC 4151.
Abstract
Between 1974 November and 1976 February the Leicester Sky Survey Instrument on Ariel V made 31 observations of NGC 4151 and 70 observations of the Coma Cluster, each observation covering approximately 3 days. Coma (3U 1257 + 39) showed good evidence for having flared by a factor of I in less than 3 days. This observation significantly limits the size of the X-ray emitting region.
