Melandri \n(INAF-OAB)\nreport on behalf of the Swift-XRT team:\n\nA second epoch of XRT data was collected on the field of the MAXI-detected\nburst: GRB 150608A (Arimoto, et al., GCN Circ. 17912) on 2015 June 13.\nThe observations consist of 2 ks of PC mode data, from T0+389 ks to \nT0+395 ks.\n\nThe X-ray source reported in GCN Circ. 17917, Bernardini et al., \nmeasured at\na mean count rate of 8.3e-01 count/sec (0.3-10 keV) in the first epoch \nof XRT\nobservations has faded to a mean count rate of (7.1e-03+/-2.2e-03) \ncount/sec\n(0.3-10 keV) in the second epoch. Assuming a power-law decay, the \ncorresponding\ndecay index is alpha=1.28 (-0.11, +0.17).  We therefore confirm that \nthis is\nthe X-ray afterglow of GRB 150608A.\n\nThis circular is an official product of the Swift-XRT team.",
