The Pierre Auger exotic events and axion quark nuggets

The Pierre Auger Observatory have reported [1-3] observation of several exotic cosmic ray -like events which apparently related to thunderstorms. These are much larger in size than conventional events, and they very distinct timing features. A possible nature the observed phenomenon is still a matter active research debates as many unusual features these hard explain. In particular, frequency appearance low (less 2 events/year), huge contrast with typical rate lightning strikes area. We propose that can be explained within so-called axion quark nugget (AQN) dark model. idea AQNs may trigger initiate special unique class during thunderstorm result ionization atmospheric molecules along its path. corresponding AQN-induced lighting flashes show some specific not shared by more frequent flashes. support this proposal demonstrating observations[1-3], including time duration consistent observations. also comment on relation AUGER Telescope Array bursts terrestrial gamma list number (such radio pulses synchronized events) directly tested future experiments. suggest use distributed acoustic sensing instruments detect must events.
