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…

Dual Origins of Rapid Flare Ribbon Downflows in an X9-class Solar Flare

Ryan J. French, William H. Ashfield, Cole A. Tamburri +4

We detect rapid downflows of 150-217 km/s in IRIS Si IV 1402.77 nm measurements of an X9-class solar flare on 2024 October 3rd. The fast redshift values persist for over 15 minutes…

Localising pulsations in the hard X-ray and microwave emission of an X-class flare

Hannah Collier, Laura A. Hayes, Sijie Yu +5

Aims: This work aims to identify the mechanism driving pulsations in hard X-ray (HXR) and microwave emission during solar flares. Here, by using combined HXR and microwave observat…
