Hard X-ray pulses from the Be/X-ray transient pulsar 2S 1417-624 are
currently begin detected by BATSE on CGRO. The first detection
was on November 12. The average pulsed flux is 16+-3 mCrab (20-50
keV). After correction with the binary orbit of Finger et al. (1996,
A&A Supp. 120, 209) the pulse timing from November 12-17 is
consistent with a constant frequency of 56.99490(9) Hz. Previous to
the current outburst the source was last detected on 1996 December 21."
