Abstract

We report the detection of coherent pulsations during an X-ray burst of the accreting Neutron Star GRO J1744-28, observed during its ongoing outburst (ATel #5790, #5810, #5845, #5858, #5883). We analyzed all the available Swift observations between February the 2nd and February the 18th 2014. In accordance with previous findings (Atel #5883), we detected 8 X-ray bursts within 5 Swift/XRT observations.
