This page allows you view selected time histories of events known as Terrestrial Gamma Flashes (TGFs). These events were discovered with BATSE (Fishman, G. J. et al., 1994, Science, 264, 1313) to originate from high in the Earth's atmosphere, and are believed to be associated with large thunderstorm activity. The image above is a Red Sprite, thought to be a possible origin of the Gamma Flashes observed with BATSE.

To view event time histories, select a BATSE trigger number, then press one of the buttons at the bottom of the page to select the appropriate dataset. You can choose from several combinations of detectors and energy channels for the time histories of each TGF:

  1. Summed over the triggered detectors, and summed over four energy channels.
  2. Summed over the triggered detectors, in four separate energy channels.
  3. Eight individual detectors, summed over four energy channels. Plots in each of the horizontal rows are from opposite-facing BATSE modules on the GRO spacecraft.
  4. Eight individual detectors, in each of the four discriminator energy channels. You can view all eight LADs and all four energy channels at the same time (32 plots), or you can choose to view each LAD separately.
