Space Weather, 2018 A large outburst of flares occurred between 4–10 September 2017 when new magnetic flux emerged into and strengthened an existing active region, National Oceanic and Atmospheric Administration Region 12673. This intense solar storm period included X9.3 (6

VERY LONG-PERIOD PULSATIONS BEFORE THE ONSET OF SOLAR FLARES [PDF]
, 2016 Solar flares are the most powerful explosions occurring in the solar system, which may lead to disastrous space weather events and impact various aspects of our Earth.

Global Properties of Solar Flares [PDF]
Space Science Reviews, 2011 This article broadly reviews our knowledge of solar flares. There is a particular focus on their global properties, as opposed to the microphysics such as that needed for magnetic reconnection or particle acceleration as such. Indeed solar flares will always remain in the domain of remote sensing, so we cannot observe the microscales directly and must ...

Fractal Reconnection in Solar and Stellar Environments
, 2016 Recent space based observations of the Sun revealed that magnetic reconnection is ubiquitous in the solar atmosphere, ranging from small scale reconnection (observed as nanoflares) to large scale one (observed as long duration flares or giant arcades ...

Retrofitting Low Carbon Aviation Fuels Processes From Natural Gas to Renewables Energy‐Based Systems
Greenhouse Gases: Science and Technology, EarlyView.ABSTRACT The aviation sector's dependence on high‐energy‐density fuels presents a challenge for decarbonization. This study evaluates the economic and environmental feasibility of retrofitting a gas‐to‐liquid (GTL) plant for low carbon aviation fuel (LCAF) production using solar electrification, an advanced reformer unit (CARGEN), and a hybrid ...

Climate and political effects on agriculture: Empirical evidence from SSA
International Studies of Economics, EarlyView.Abstract The most of Sub‐Saharan African (SSA) countries have been affected by climate change and food insecurity problems due to the reduction of production and productivity of cereal crops in the continent. The purpose of this research was to examine the short‐run and long‐run effects of climate change on agricultural productivity in 24 selected SSA ...

A Statistical Study of Photospheric Magnetic Field Changes During 75 Solar Flares [PDF]
, 2017 Abrupt and permanent changes of photospheric magnetic fields have been observed during solar flares. The changes seem to be linked to the reconfiguration of magnetic fields, but their origin is still unclear.

IMPULSIVITY PARAMETER FOR SOLAR FLARES [PDF]
The Astrophysical Journal, 2016 ABSTRACT Three phases are typically observed during solar flares: the preflare, impulsive, and decay phases. During the impulsive phase, it is believed that the electrons and other particles are accelerated after the stored energy in the magnetic field is released by reconnection.
