Observing terrestrial gamma ray flashes



Terrestrial Gamma Ray Flash Workshop; Huntsville, Alabama, 13–14 July 2011 Terrestrial gamma ray flashes (TGFs) were the focus of a workshop held at the University of Alabama in Huntsville (UAH), with observation and theory well represented by the 38 attendees. Discovered in 1991 as brief (submillisecond), bright flashes of gamma rays detected over regions of thunderstorm activity by the spaceborne Burst And Transient Source Experiment, TGFs may be entering an observational golden era. Three space-based gamma ray telescopes currently make TGFs a scientific priority.
