report for the Compton GRO Observatory BATSE pulsar team: "Pulsed
hard x-ray flux is currently being detected from the transient
Be/x-ray pulsar 4U 0115+634.  The source was detected on Aug. 10,
when the rms pulsed flux (20-50 keV) was approximately 25 mCrab.
This is the first detection by BATSE of this source since a pair of
outbursts that occurred during the interval 1995 Nov. 18-1996 Jan.
9 (IAUC 6266).  On 1996 Aug. 12, the rms pulsed flux (20-50 keV)
was approximately 30 mCrab.  The pulse frequencies observed from
Aug. 10 to 12 are consistent with a neutron-star spin rate of
0.27666712 +/- 0.00000022 Hz and no detectable spin-up, using the
binary orbital ephemeris of Rappaport et al. (1978, Ap.J. 211, L1)
with the epoch of periastron passage updated to 1996 Aug. 5.583 TBD."
