GRO J2058+42, a transient 198 second x-ray pulsar, was discovered by BATSE during a giant outburst in 1995 September-October. The total flux peaked at about 300 mCrab (20-50 keV) as measured by Earth occultation. The pulse period decreased from 198 s to 196 s during the 46-day outburst. BATSE has observed five additional weak outbursts from GRO J2058+42 with peak pulsed fluxes of about 15 mCrab (20-50 keV) that were spaced by about 110 days. The periodicity of the outbursts allowed a ToO observation by the Rossi X-ray Timing Explorer (RXTE) Proportional Counter Array (PCA) which localized the source to a 4' error circle. We present pulse frequency history, flux histories from pulsed and Earth occultation data, and representative pulse profiles.
