Abstract (from CDS):

During a serendipitous observation of the BeppoSAX Wide Field Cameras, a very long typeI X-ray burst was observed from the low mass X-ray binary Serpens X-1. The burst lasted for approximately 4 hours and had an exponential decay time of 69±2min (2-28keV). The bolometric peak-luminosity is (1.6±0.2)x1038erg/s and the fluence (7.3±1.4)x1041erg. The first ``normal" typeI burst was observed 34 days after the superburst. This is in rough agreement with recent predictions for unstable carbon burning in a heavy element ocean.
