Abstract

Since 2015 June 27 the outburst of V404 Cyg has been declining from its outburst peak (ATel #7729, #7731, #7733, #7740, #7752). We report here on the first seven Swift XRT Photon Counting mode observations taken both from public DDT and guest investigator ToO (PI: Miller-Jones) programs after the source began to decline.
