Cycle 23 Variation in Solar Flare Productivity
, 2013 The NOAA listings of solar flares in cycles 21-24, including the GOES soft X-ray magnitudes, enable a simple determination of the number of flares each flaring active region produces over its lifetime.

Observations of an Eruptive Solar Flare in the Extended EUV Solar Corona [PDF]
, 2017 We present observations of a powerful solar eruption, accompanied by an X8.2 solar flare, from NOAA Active Region 12673 on 2017 September 10 by the Solar Ultraviolet Imager (SUVI) on the GOES-16 spacecraft.

Do Financialization and Innovation Enhance Environmental Sustainability in Sub‐Saharan Africa?
Thunderbird International Business Review, EarlyView.ABSTRACT This study addresses the perception of Sub‐Saharan Africa (SSA) as a region with limited financial capabilities and technological advancement to enhance environmental sustainability. Conducted across 24 SSA countries from 2000 to 2021, the research employs instrumental IV and panel quantile regressions.

No Evidence Supporting Flare Driven High-Frequency Global Oscillations
, 2012 The underlying physics that generates the excitations in the global low-frequency, < 5.3 mHz, solar acoustic power spectrum is a well known process that is attributed to solar convection; However, a definitive explanation as to what causes excitations in

Spectroscopic Observations of a Current Sheet in a Solar Flare [PDF]
, 2018 The current sheet is believed to be the region of energy dissipation via magnetic reconnection in solar flares. However, its properties, for example, the dynamic process, are not fully understood. Here, we report a current sheet in a solar flare (SOL2017-

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.Summary Background Erythropoietic protoporphyria (EPP) is a rare genetic disorder characterized by severe phototoxic reactions that occur within minutes of light exposure. In clinical studies, afamelanotide has been shown to prolong pain‐free sun exposure, improve quality of life, and reduce the frequency and severity of phototoxic reactions ...

Evolution of coronal magnetic field parameters during X5.4 solar flare
Frontiers in Astronomy and Space Sciences, 2023 The coronal magnetic field over NOAA Active Region 11,429 during a X5.4 solar flare on 7 March 2012 is modeled using optimization based Non-Linear Force-Free Field extrapolation. Specifically, 3D magnetic fields were modeled for 11 timesteps using the 12-

Solar Flares and Coronal Mass Ejections: A Statistically Determined Flare Flux-CME Mass Correlation [PDF]
, 2010 In an effort to examine the relationship between flare flux and corresponding CME mass, we temporally and spatially correlate all X-ray flares and CMEs in the LASCO and GOES archives from 1996 to 2006.

Deep Learning Based Solar Flare Forecasting Model. I. Results for Line-of-sight Magnetograms
, 2018 Solar flares originate from the release of the energy stored in the magnetic field of solar active regions, the triggering mechanism for these flares, however, remains unknown.
