Pulsed X-ray flux is being detected by Fermi/GBM from the transient binary pulsar IGR J19294+1816. In the data of February 7, we measure a 12 - 50 keV pulsed flux of 15 +/- 2 mCrab with a barycentric frequency of 80.2754(6) mHz.

The source has an outburst period of about 117 days (Corbet & Krimm, ATel #2008). The last reported outburst began 2010 October 27 (ATel #2985). This was followed by a previously unreported outburst that was detected with Fermi/GBM on 2010 February 14.
