Coincident optical monitoring of GRB error boxes.
Abstract
The authors have established an array of telescopes which will photoelectrically monitor known GRB positions and detect any flash which is brighter than 10th magnitude and persists longer than 10 milliseconds. Since at least two widely-separated telescopes will monitor the same field, a true GRB flash would simultaneously trigger more than one instrument. When a trigger occures, the light-curve as well as the exact time at which the event occurred is stored on a computer disk and a photograph of the GRB field is taken. From November 1985 to November 1989, 1063 hours GRB regions were monitored.No coincident trigger due to an event in a GRB error box has been recorded.
