Yesterday evening I have found a saturation in a single Geiger of the independent URadmonitor website. It matches perfectly the time of Fermi GRB190429.74 : peak at 21:04 UT and the same for the network.

It has to be noted that there is a gap between 17:47 and 21:35 UT in the Geiger that suggests a great time of adjustment of the beacon due to the immediate variation. We see then a time of stagnation around 9 milliSv/h and then a definitive, immediate fall back to normal.

Another strong one ongoing (end of May, beginning of June 2019) in the Southern Hemisphere… Long duration.
