Information About 171 GRBs/SGRs/Transients for 2018

This page contains links to files of all the Circulars on the given GRB/transient.
This includes the circulars published by the mission(s)-instrument(s) making a detection,
and by the follow-up observers.

For each GRB/transient, the link label contains a series of strings.
These strings show which mission-instrument made the intial detection,
then zero or more strings showing which other missions-instruments made detections, and
the "Optical" string if there were any ground-based optical detections (or "optical" if only upper limits),
ditto "Radio" or "radio" for detection or upper limit, and "z=n.nnn" for a redshift measurement.
