INTERPRETATION OF THE DISTURBANCE IN GALACTIC COSMIC RAYS OBSERVED ON VOYAGER 1 BEYOND THE HELIOPAUSE

We present a possible explanation for the transient increase in the galactic cosmic ray flux observed by Voyager 1 (V1) beyond the heliopause, in 2013 March. We suggest that this disturbance may be caused by a propagating disturbance in the interstellar magnetic field, of heliospheric origin. A mode...

Summary:We present a possible explanation for the transient increase in the galactic cosmic ray flux observed by Voyager 1 (V1) beyond the heliopause, in 2013 March. We suggest that this disturbance may be caused by a propagating disturbance in the interstellar magnetic field, of heliospheric origin. A model in which a magnetic disturbance, propagating outward from the heliosphere into the very-local interstellar plasma, affects the galactic cosmic rays is presented. We also discuss the possibility that this event is related to the plasma-wave event observed some 25 days later by the PWS experiment on V1.
