INTEGRAL and RXTE observations of A0535+26
Abstract
The Be/X-ray binary A0535+26 is currently undergoing an outburst, first reported by Fermi/GBM on July 26 (ATel #2142). After its last giant outburst in 2005 (ATel #504), the source has shown occasional outbursts associated with the periastron passage (ATel #1725). The current outburst is the fourth in a series of weaker outbursts close to periastron, but is unusual by starting at an earlier orbital phase (ATel #2142) and by a peculiar lightcurve.
