On the short term modulation of cosmic rays by high-speed streams at the Pierre Auger surface array detectors
M. N. de Oliveira, C. R. A. Augusto, C. E. Navia +1
We present an analysis of the short-term modulation (one rotation of Bartels-27 days) of the galactic cosmic rays (GCR) by the solar wind, based on the cosmic ray rates observed by…
Possible GeV counterpart at the ground level associated with Fermi LAT gamma-ray bursts
C. R. A. Augusto, C. E. Navia, M. N. de Oliveira +3
From June 2014 to February 2017, the Fermi LAT detected 46 gamma-ray bursts (GRBs) with photon energies above 20 MeV, and the trigger coordinates of seven of them were within the F…
The 2015 Summer Solstice Storm: one of the major geomagnetic storms of solar cycle 24 observed at ground level
C. R. A. Augusto, C. E. Navia, M. N. de Oliveira +8
We report on the 22-23 June 2015 geomagnetic storm. There has been a shortage of intense geomagnetic storms during the current solar cycle 24 in relation to the previous cycle. Thi…
Relativistic proton levels from region AR 12673 (GLE \#72) and the heliospheric current sheet as a SunEarth magnetic connection
C. R. A. Augusto, C. E. Navia, M. N. de Oliveira +4
On 2017 September 10 Neutron Monitors (NMs) apparatus located at ground level and high latitudes detected an increase in the counting rate associated to solar energetic particles (…
