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 (…
Muon Excess at Sea Level during the Progress of a Geomagnetic Storm and High Speed Stream Impact Near the Time of Eath's Heliospheric Sheet Crossing
C. R. A. Augusto, C. E. Navia, M. N. de Oliveira +3
In this article we present results of the study on the association between the muon flux variation at ground level, registered by the \textit{\textit{New-Tupi}} muon telescopes ($2…
Prompt emission from GRB 150915A in the GeV energy range detected at ground by the New-Tupi detector: A review
C. R. A. Augusto, C. E. Navia, M. N. de Oliveira +3
Since 2014, a new detector (New-Tupi) consisting of four plastic scintillators () placed in pairs and located in Niteroi, Rio de Janeiro, Brazil, has b…
Was the GLE on May 17, 2012 linked with the M5.1-class flare the first in the 24th solar cycle?
C. R. A. Augusto, V. Kopenkin, C. E. Navia +8
On May 17, 2012 an M5.1-class flare exploded from the sun. An O-type coronal mass ejection (CME) was also associated with this flare. There was an instant increase in proton flux w…
