During a serendipitous observation of the BeppoSAX Wide Field Cameras, a very long type I 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 $69\pm2$ min (2–28 keV). The bolometric peak-luminosity is ($1.6\pm0.2)\times10^{38}$ ${\rm erg\,s}^{-1}$ and the fluence ($7.3\pm1.4)\times10^{41}$ erg. The first “normal" type I burst was observed 34 days after the superburst. This is in rough agreement with… Expand
