The RAEGE network (Portuguese/Spanish acronym for Atlantic Network of Geodynamic and Space Stations) is a cooperation project between the National Geographic Institute of Spain and the Regional Government of the Azores. The Santa Maria station observed emissions at 6668.519 MHz and 12178.593 MHz frequencies towards several sources in which flux d...

The Electron Proton and Alpha Monitor (EPAM) onboard the Advanced Composition Explorer (ACE) spacecraft detected a Solar Energetic Particle Event (SEP) on 2015 October 29. The EPAM telescopes detected near relativistic electrons, and protons with energies above 1 GeV. Although no statistically significant enhancement in the count rates of neutron m...

On 2017 September 10, the neutron detectors on the Earth's surface detected the second Ground Level Enhancement (GLE) of the solar cycle 24. This GLE was associated with a beam-like near relativistic electron event seen by the Electron, Proton, and Alpha Monitor (EPAM) particle instrument in the Advanced Composition Explorer (ACE). All the electron...

The PLOAD — Portuguese Language Office of Astronomy for Development — was established in 2015 by the International Astronomical Union (IAU) with the goal of promoting astronomy as a tool for sustainable development in Portuguese-speaking countries.

A explosão solar é um dos fenômenos energéticos mais intensos nas regiões ativas da atmosfera solar. As imagens destas regiões em extremo ultravioleta e raio-X moles revelam a complexidade da configuração dos campos magnéticos. Durante as explosões, a geometria do campo magnético pode ser analisada através da sua componente de emissão em micro-onda...

This material was produced under the development project called "As-troEcoTourism in Mozambique" (AET@MOZ) funded by the DARA (De-velopment in Africa with Radio Astronomy) and OAD (Office of Astronomy for Development). The AET@MOZ project aims to use astronomy as a tool to promote local ecotourism in Mozambique, adding observations of the night sky...

We developed a database of pre-calculated flare images and spectra exploring a set of parameters which describe the physical characteristics of coronal loops and accelerated electron distribution. Due to a large number of parameters involved in describing the geometry and the flaring atmosphere in the model used (Costa et al. 2013), we built a larg...

A Solar Energetic Particle (SEP) was detected by the Electron Proton and Alpha Monitor (EPAM) onboard of the Advanced Composition Explorer (ACE) spacecraft on 2013 May 22 both in the electrons and ion channels. In the electrons channels, it is a prompt fast rising highly isotropic event. There is an evidence in the ion channels of protons with ener...
