  We describe the evolutionary progression of an outburst of the Rapid Burster.
Four outbursts have been observed with the Rossi X-Ray Timing Explorer between
February 1996 and May 1998, and our observations are consistent with a standard
evolution over the course of each. An outburst can be divided into two distinct
phases: Phase I is dominated by type I bursts, with a strong persistent
emission component; it lasts for 15-20 days. Phase II is characterized by type
II bursts, which occur in a variety of patterns. The light curves of
time-averaged luminosity for the outbursts show some evidence for reflares,
similar to those seen in soft X-ray transients. The average recurrence time for
Rapid Burster outbursts during this period has been 218 days, in contrast with
an average ~180 day recurrence period observed during 1976-1983.
