NuSTAR observations of a repeatedly microflaring active region
Kristopher Cooper, Iain G. Hannah, Brian W. Grefenstette +6
We investigate the spatial, temporal, and spectral properties of 10 microflares from AR12721 on 2018 September 9 and 10 observed in X-rays using the Nuclear Spectroscopic Telescope…
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…
A Space-based All-sky MeV gamma-ray Survey with the Electron Tracking Compton Camera
Kenji Hamaguchi, Toru Tanimori, Atsushi Takada +8
A sensitive survey of the MeV gamma-ray sky is needed to understand important astrophysical problems such as gamma-ray bursts in the early universe, progenitors of Type Ia supernov…
Joint X-ray, EUV and UV Observations of a Small Microflare
Iain G. Hannah, Lucia Kleint, Säm Krucker +5
We present the first joint observation of a small microflare in X-rays with the Nuclear Spectroscopic Telescope ARray (NuSTAR), UV with the Interface Region Imaging Spectrograph (I…
Hard X-Ray Constraints on Small-Scale Coronal Heating Events
Andrew J. Marsh, David M. Smith, Lindsay Glesener +7
Much evidence suggests that the solar corona is heated impulsively, meaning that nanoflares may be ubiquitous in quiet and active regions (ARs). Hard X-ray (HXR) observations with…
