Thefirst GLE o f the new 24"' solar cycle of EO in GLE71 can be explained by the fact that the event GLE71 has occurred in weak eruption flare (1F/M5.1), which had lower plasma velocities. Conclusions Analysis o f the first event GLE (17.05.2012) in the new 24th solar cycle is presented. The spectra and the pitch-angle distribution of RSP during the event were obtained. Feature of this event is the exponential form o f the RSP spectrum during GLE, as well as the intensity gap at pitch angles -90°, which is observed on the initial phase of GLE. Fig. 3 GLE71.

Black dot lines are isogons with its pitch angle values. Bold green numbers on the cones indicate increase magnitudes of corresponding stations. The numbers are set at station sensitivity maxima to the derived spectrum at 02:20 UT. Distribution of these numbers along the map has a gap at ~90° pitch angles. A ckn ow led gm en ts.
