Pulsation from the transient Be/X-ray binary pulsar GX 304-1 is being detected with Fermi/GBM. Our first detection since the giant outburst of 2012 October - November (ATels #4420, #4547) was in the data of February 13, with a barycentric frequency of 3.6408(6) mHz (period = 274.66(5)s), and an r.m.s. pulsed flux of 23 +/- 5 mCrab in the 12-50 keV band.
