Abstract

Swift observed the recent optical transient (ATel #1501) in M82 for 4900 sec and made no detection of X-rays from the source. The upper limit corresponds to approximately 2*10^-3 cts/sec (99% confidence level), which corresponds to a .1-10 keV X-ray luminosity of 1.5 * 10^38 ergs/sec for a 1 keV blackbody spectrum or for a Gamma=1.7 power law, assuming the foreground absoprtion of 5*10^20 cm^-3.
