RXTE observed the new INTEGRAL source IGR J19294+1816 (ATEL #1997) for 2.5 ksec starting on March 31, 2009 at 07:51:28 (UT). A second 3.2 ksec observation began at 17:02:24 (UT) on the same day. We detect strong pulsations in the first observation with a barycentric period of 12.44 s. The background subtracted, average pulsation amplitude during this observation is 37%. We also detect the first harmonic, but with an amplitude smaller by a factor of approximately 4.
