XRF 020903
A. M. Soderberg et al. reported in GCN 1554 that they discovered a possible
optical counterpart of the X-ray flash of 3 September 2002. Their additional
observations revealed a brightening of the object, which they proposed
to be a supernova associated with this XRF. If the optical transient is
indeed associated with XRF020903, it is the first known optical afterglow
of an XRF, and may be the most nearby cosmological high energy transient
known yet (vsnet-campaign-sn
