NuSTAR Observation of Energy Release in Eleven Solar Microflares
Jessie Duncan, Lindsay Glesener, Brian W. Grefenstette +6
Solar flares are explosive releases of magnetic energy. Hard X-ray (HXR) flare emission originates from both hot (millions of Kelvin) plasma and nonthermal accelerated particles, g…
Hot X-ray Onsets of Solar Flares
Hugh S. Hudson, Paulo J. A. Simoes, Lyndsay Fletcher +2
The study of the localized plasma conditions before the impulsive phase of a solar flare can help us understand the physical processes that occur leading up to the main flare energ…
NuSTAR Observation of a Minuscule Microflare in a Solar Active Region
Kristopher Cooper, Iain G. Hannah, Brian W. Grefenstette +5
We present X-ray imaging spectroscopy of one of the weakest active region (AR) microflares ever studied. The microflare occurred at 11:04 UT on 2018 September 9 and we studie…
Accelerated electrons observed down to <7 keV in a NuSTAR solar microflare
Lindsay Glesener, S"am Krucker, Jessie Duncan +6
We report the detection of emission from a non-thermal electron distribution in a small solar microflare (GOES class A5.7) observed by the Nuclear Spectroscopic Telescope Array (Nu…
