The taxonomy of optical emission detected during the critical first few minutes after the onset of a gamma-ray burst (GRB) defines two broad classes: prompt optical emission correlated with prompt gamma-ray emission, and early optical afterglow emiss

The prompt optical emission that arrives with gamma-rays from a cosmic gamma-ray burst (GRB) is a signature of the engine powering the burst, the properties of the ultra-relativistic ejecta of the explosion, and the ejecta's interactions with the sur

We report on the discovery of an outburst from a previously unknown high- latitude CV we designate ROTSE3 J015118.59-022300.1. The object was first detected on 2001 Oct 13.291 at m-ROTSE3=14.71+-0.06, after which it faded by more than 2 magnitudes ov
