Abstract Monitoring observations with the PCA instrument (2-60 keV) aboard the Rossi X-ray timing Explorer performed between 2008, February 17 and 26 (43.5 ks exposure in total) revealed the spin-down rate of the newly discovered 70.5 ms pulsar in AX J1838.0-0655 (Gotthelf et al.; ATEL #1392). We obtained a phase coherent timing solution yielding a greatly improved pulse period of 70.4982056(2) ms and a period derivative of 4.94(5)E-14 s/s evaluated at the epoch MJD 54513.0 (TDB).
