Over the last years Athens Cosmic Ray Group of National & Kapodistrian University has implemented a warning tool called GLE Alert, which is highly credible application that issues alerts when ground level enhancement (GLE) starts due to very high energy solar energetic particles reaching Earth. This warns intensity particle event up several minutes before it reaches near near-Earth space environment. In this work, an assessment latest updated version Alert++, presented. Alert++ federated...
Many scientific investigations have focused on how space weather phenomena, taking place in the vicinity of Earth, may influence different aspects life Earth and presumably human health itself. From 2005, National Kapodistrian University Athens has established an important position field these by collaborating with various scientists Institutes, both international domestic, heliobiological projects. In this work, Cosmic Ray Group co-operated medical staff from hospitals clinics around...
A ground-level enhancement (GLE) event is a sudden increase in cosmic ray intensity originated by solar sources and recorded ground-based detectors. GLEs are invariably associated with large flares that can release accelerate particles at high energies. The minimum kinetic energy of reaching the Earth’s surface >433 MeV sea level about 300 MeV/n high-mountain altitude 3000 m a.s.l. Even though these abrupt events linked to activity quite rare, they have great impact on technological...
After a prolong and deep solar minimum at the end of cycle 23, current 24 is one lowest cycles. The two periods mini-maximum are connected by period increasing activity. In this work, Forbush decreases cosmic ray intensity during from January 2008 to December 2014 studied. A statistical analysis 749 events using IZMIRAN database effects obtained processing data worldwide neutron monitor network global survey method performed. further study that happened on Sun affected interplanetary space,...
A Ground Level Enhancement (GLE) event can be observed as an increase in the background of ground-based neutron monitor observations and is often associated with >500 MeV space-based proton flux measurements. GLE events begin very high-energy SEP GeV protons. For such to detected at sea level, energies must exceed about 433 MeV. To mitigate for potential impacts on space systems, avionics human health, monitoring these particles essential, so having reliable real-time warning systems....
Abstract A Ground Level Enhancement (GLE) event can be observed as an increase in the background of ground‐based neutron monitor observations and is often associated with >500 MeV space‐based proton flux measurements. GLE events begin very high‐energy SEP GeV protons. For such to detected at sea level, energies must exceed about 433 MeV. Since increased particles a major problem technology space on Earth pose threat for human health, developing real time warning systems great importance....
We study the bulk acceleration in relativistic axisymmetric magnetized outflows, by solving momentum equation along flow, so-called wind equation. The solutions for Lorentz factor depend on geometry of field/streamlines through "bunching function" S. investigate general characteristics S function and how its choice affects acceleration. In our study, various fast rise slow decay examples are selected S, with a global maximum near magnetosonic critical point, as required from regularity...
