在近6年的观测中，我发现了一个来自X射线爆发GX 3+1的长X射线耀斑。该事件的峰值通量约为1.1Crab（1.5-12 keV），持续时间为4.4 - 16.2小时，源距为5 kpc时的注量大于5× 1041 erg。在类指数衰减期间，具有1.6小时的指数衰减时间，可见光谱软化。GX 3+1上ASM的总有效暴露时间估计约为一年。耀斑具有最近在其他X射线爆发源中发现的所谓超级爆发的所有特征。
I found one long X-ray flare from the X-ray burster GX 3+1 in almost 6 years of observations with the RXTE All Sky Monitor (ASM). The event had a peak flux of about 1.1 Crab (1.5-12 keV), lasted between 4.4 and 16.2 hoursand exhibited a fluence of more than about 5×10 4 1 erg for a source distance of 5 kpc. During the exponential-like decay, with an exponential decay time of 1.6 hours, spectral softening is seen. The total ASM effective exposure time on GX 3+1 is estimated to be around a year. The flare bears all the characteristics of the recently discovered so-called superbursts in other X-ray burst sources.
