Establishing a phase-coherent timing solution for a bright, unusual MSP

We have discovered a bright nearby eclipsing millisecond pulsar with a non-degenerate companion, a key "missing link" in the evolution of low-mass X-ray binaries into radio millisecond pulsars. Its companion is a 17th magnitude star, and the system appears to have had an accretion disc as recently as 2001. Phase-coherent timing promises to elucidate the dynamics and the energetics of this system. We request six half-hour L-band observations over the next two months.
