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…
A sudden fine-scale bright kernel captured by Hi-C Flare in 11 MK emission during an M1.6-class solar flare's post-maximum phase
Sanjiv K. Tiwari, Navdeep K. Panesar, Ronald L. Moore +17
On April 17, 2024, the third successful Hi-C sounding rocket flight, Hi-C Flare, recorded coronal images in Fe XXI 129 A emission from 11 MK plasma during the post-maximum phase of…
Rapid variations of Si IV spectra in a flare observed by IRIS at a sub-second cadence
Juraj Lorincik, Vanessa Polito, Bart De Pontieu +2
We report on observations of highly-varying Si IV 1402.77 line profiles observed with the Interface Region Imaging Spectrograph (IRIS) during the M-class flare from 2022 January 18…
Blueshifted Si IV 1402.77Å line profiles in a moving flare kernel observed by IRIS
Juraj Lörinčík, Jaroslav Dudík, Vanessa Polito
We analyze spectra of a slipping flare kernel observed during the 2015 June 22 M6.5-class flare by the Interface Region Imaging Spectrograph (IRIS). During the impulsive and peak p…
Saddle-shaped solar flare arcades
Juraj Lörinčík, Jaroslav Dudík, Guillaume Aulanier
Arcades of flare loops form as a consequence of magnetic reconnection powering solar flares and eruptions. We analyse the morphology and evolution of flare arcades that formed duri…
Electron Densities in the Solar Corona Measured Simultaneously in the Extreme-Ultraviolet and Infra-Red
Jaroslav Dudík, Giulio Del Zanna, Ján Rybák +5
Accurate measurements of electron density are critical for determination of the plasma properties in the solar corona. We compare the electron densities diagnosed from Fe XIII line…
Imaging evidence for solar wind outflows originating from a CME footpoint
Juraj Lörinčík, Jaroslav Dudík, Guillaume Aulanier +2
We report on the Atmospheric Imaging Assembly (AIA) observations of plasma outflows originating in a coronal dimming during the 2015 April 28th filament eruption. After the filamen…
Multi thermal atmosphere of a mini solar flare during magnetic reconnection observed with IRIS
Reetika Joshi, Brigitte Schmieder, Akiko Tei +4
The Interface Region Imaging Spectrograph(IRIS) with its high spatial and temporal resolution brings exceptional plasma diagnostics of solar chromospheric and coronal activity duri…
Signatures of Helium continuum in cool flare loops observed by SDO/AIA
Petr Heinzel, Pavol Schwartz, Juraj Lörinčík +3
We present an analysis of off-limb cool flare loops observed by SDO/AIA during the gradual phase of SOL2017-09-10T16:06 X8.2-class flare. In the EUV channels starting from the 335…
Observation of all pre- and post-reconnection structures involved in three-dimensional reconnection geometries in solar eruptions
Jaroslav Dudik, Juraj Lorincik, Guillaume Aulanier +2
We report on observations of the two newly-identified reconnection geometries involving erupting flux ropes. In 3D, a flux rope can reconnect either with a surrounding coronal arca…
Manifestations of three dimensional magnetic reconnection in an eruption of a quiescent filament: \\ Filament strands turning to flare loops
Juraj Lorincik, Jaroslav Dudik, Guillaume Aulanier
We report on observations of conversion of bright filament strands into flare loops during 2012 August 31 filament eruption. Prior to the eruption, individual bright strands compos…
Velocities of flare kernels and the mapping norm of field line connectivity
Juraj Lörinčík, Guillaume Aulanier, Jaroslav Dudík +2
We report on observations of flare ribbon kernels during the 2012 August 31 filament eruption. In the 1600\,Å and 304\,Å channels of the Atmospheric Imaging Assembly, flare kernels…
Imaging and Spectroscopic Observations of a Transient Coronal Loop: Evidence for the Non-Maxwellian -Distributions
Jaroslav Dudik, Simon Mackovjak, Elena Dzifcakova +8
We report on the SDO/AIA and Hinode/EIS observations of a transient coronal loop. The loop brightens up in the same location after the disappearance of an arcade formed during a B8…
