and [[*ROSAT*]{}]{}, pulsations had not been detected until the [[*RXTE* ]{}]{} monitoring data presented here.

A single outburst was detected from SMC X-2, lasting from 2000 January 24 to April 23. During this outburst, the luminosity (2-25 keV) reached a peak of 4.7 $\times 10^{38}{\mbox{${{\rm\thinspace erg}}{{\rm\thinspace s}}^{-1}$}}$, and was detected down to a level of 5.7$\times 10^{37}{\mbox{${{\rm\thinspace erg}}{{\rm\thinspace s}}^{-1}$}}$ before disappearing from view sometime before May 5. The detection of SMC X-2 with the [[*RXTE* ]{}]{}All-Sky Monitor (*ASM*) followed by discovery of 2.37 second pulsations co-incident with the known position of SMC X-2 from *PCA* scans and targeted observations was presented by @Corbet01_x2, along with contemporaneous optical observations confirming the counterpart originally proposed by @Murdin79. An [[*ASCA* ]{}]{}observation on April 24 by @Yokogawa01 confirmed the 2.37 s pulsar to be exactly coincident with the position of SMC X-2 determined by *SAS-3* and [[*ROSAT* ]{}]{}.

From the SMC monitoring data, pulsations with a period of 2.37s were detected with the PCA during 13 observations between MJD 51567 and MJD 51657. Of these, 9 were pointings at the regular monitoring position (position 5, see Table \[tab:positions\]), plus 2 targeted pointings centered on SMC X-2, and 2 sets of scans across the source
