Quasi-periodic pulsations and three-dimensional magnetic reconnection during 2022 March 31 flare observed by IRIS & STIX

Juraj Lorincik, Hannah Collier, Vanessa Polito +3

Apparent slipping motions of flare ribbon kernels and the formation of hard X-ray (HXR) footpoints are important signatures of magnetic reconnection in solar flares. Ultraviolet (U…

Observations of a Faint Nonthermal Onset before a GOES C-class Flare

Natália Bajnoková, Iain G. Hannah, Hannah Collier +6

We present analysis of a GOES C1-class flare from 2022 September 6, which was jointly observed as occulted by Nuclear Spectroscopic Telescope ARray (NuSTAR) and on-disk by Spectrom…

Spatiotemporal evolution of UV pulsations and their connection to 3D magnetic reconnection and particle acceleration

Stefan Purkhart, Hannah Collier, Laura A. Hayes +3

Quasi-periodic pulsations (QPPs) are a common feature of impulsive solar flare emissions, yet their driving mechanism(s) remain unresolved. We study long-period (3.4 min) QPPs in t…
