GRB 830801

GRB 830801 is a gamma-ray burst that occurred on 1 August 1983. It is one of the brightest GRB events known.

It had a peak flux of 3.0 photons·cm−2·s−1·keV−1 averaged from 50 to 300 keV, a dead time correction by a factor of 1.9, and a smooth light curve for the peak 256 ms time interval. The peak flux P256 was around 1,400 photons·s−1·cm−2.

This was also the first detection of the influence of a gamma burst on the upper atmosphere.
