New measurement of the period for the 4th ULX pulsar - the supernova impostor SN2010da in NGC 300
Abstract
Following the discovery (Atel #11158) of the new (fourth) ULX pulsar (in the peculiar supergiant X-ray binary known as the supernova impostor SN 2010da located in NGC 300, at a distance of 1.86 Mpc) we note that SWIFT/XRT observed this galaxy again on April 16, 2017, and detected the source still in a bright X-ray state.
