| Abstract |
RXTE observations of the bursting accreting millisecond X-ray pulsar IGR J17511-3057 (ATEL #2196, #2197, #2198) showed a short Type I X-ray burst on September 14th 2009. We detect strong burst oscillations at 245 Hz, very close to the spin frequency. Maximum Leahy power is in the range 130-215 in 3 independent consecutive 4s bins during the burst (using all photons in the 2-60 keV band), putting the detection beyond doubt. Burst oscillation amplitude exceeds 10% rms in this energy band.
