Considering the observations of the transient source in the globular cluster Terzan 5 (ATEL #2919, #2920, #2922, #2924, #2929, #2932, #2933, #2935, #2937), performed by RXTE between 2010 Oct 13.009 and 14.879 (for a total exposure of 23ks), we could derive a preliminary estimate of the orbital solution of the 11.043847(41) Hz, newly discovered pulsar. As the ephemerides of the satellite have not been released yet at the time of writing this telegram, we added to the circular model considered to describe the orbit of the pulsar, also a sinusoidal component of period 93.3 +/- 0.7 min to take into account the satellite orbit.

Abstract
Considering the observations of the transient source in the globular cluster Terzan 5 (ATEL #2919, #2920, #2922, #2924, #2929, #2932, #2933, #2935, #2937), performed by RXTE between 2010 Oct 13.009 and 14.879 (for a total exposure of 23ks), we could derive a preliminary estimate of the orbital solution of the 11.043847(41) Hz, newly discovered pulsar. As the ephemerides of the satellite have not been released yet at the time of writing this telegram, we added to the circular model considered to describe the orbit of the pulsar, also a sinusoidal component of period 93.3 +/- 0.7 min to take into account the satellite orbit.
