J. Tueller, Goddard Space Flight Center (GSFC), on behalf of the InFOCuS team (a collaboration between NASA/GSFC, Nagoya University, JAXA/ISAS, and the University of Pennsylvania), reports that observations of the transient x-ray pulsar 4U 0115+63 (cf. IAUC 3161, 7116) were made with a balloon-borne hard-x-ray focusing telescope (launched from Ft. Sumner, NM) for 3200 s starting at Sept. 17.19 UT. The pulsar is continuing an outburst first detected by RXTE/ASM during Aug. 27-Sept. 2 (cf. http://xte.mit.edu/XTE.html). A preliminary 20-50-keV flux of 3.18 (+0.375/-0.324) x 10**-9 erg cm**-2 s**-1, consistent with the RXTE/ASM data, was derived from data obtained during Sept. 17.20- 17.22. A summed-epoch analysis yields a preliminary pulse period of 3.616 ± 0.001 s.
