  Rossi X-ray Timing Explorer All Sky Monitor observations of SMC X-2 show that
the source experienced an outburst in January to April 2000 reaching a peak
luminosity of greater than ~10^38 ergs s^-1. RXTE Proportional Counter Array
observations during this outburst reveal the presence of pulsations with a
2.37s period. However, optical photometry of the optical counterpart showed the
source to be still significantly fainter than it was more than half a year
after the outburst in the 1970s when SMC X-2 was discovered.
