First joint X-ray solar microflare observations with NuSTAR and Solar Orbiter/STIX
Natália Bajnoková, Iain G. Hannah, Kristopher Cooper +5
We present the first joint spectral and imaging analysis of hard X-ray (HXR) emission from 3 microflares observed by the Nuclear Spectroscopic Telescope ARray (NuSTAR) and Solar Or…
Detecting non-thermal emission in a solar microflare using nested sampling
Kristopher Cooper, Iain G. Hannah, Lindsay Glesener +1
Microflares are energetically smaller versions of solar flares, demonstrating the same processes of plasma heating and particle acceleration. However, it remains unclear down to wh…
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…
