Preliminary results are reported on the spectral and timing properties of thespectacular 2001 superburst of 4U 1636-536 as seen by the RXTE/PCA. The(broad-band) power-spectral and hardness properties during the superburst arecompared to those just before and after the superburst. Not all of thesuperburst emission can be fitted by pure black-body radiation. We alsogathered BeppoSAX/WFC and RXTE/ASM data, as well as other RXTE/PCA data,obtained days to months before and after the superburst to investigate thenormal X-ray burst behavior around the time of the superburst. The first normalX-ray burst after the 2001 superburst was detected 23 days later. Duringinspection of all the RXTE/ASM data we found a third superburst. Thissuperburst took place on June 26, 1999, which is ~2.9 yrs after the 1996superburst and ~1.75 yrs before the 2001 superburst. The above findings are thestrongest constraints observed so far on the duration of the cessation ofnormal X-ray bursts after a superburst and the superburst recurrence times.Comment: 4 pages, 4 figures,to appear in the proceedings of "X-Ray Timing  2003: Rossi and Beyond", eds.
