Signatures of photospheric convection throughout the solar atmosphere: the EVE Sun-as-a-star mHz continuum
Hugh Hudson, Anne-Marie Broomhall, Lyndsay Fletcher +5
Convectively driven motions in the solar photosphere can generate broadband Doppler variability across the chromosphere, transition region and corona. Here we investigate this vari…
First time delay observation between two mid-infrared channels in solar flare footpoints
Miguel Rojas-Quesada, Lyndsay Fletcher, Hugh Hudson +2
The strong correlation between energy injection and mid-infrared (mid-IR) emission observed during solar flares can be used to probe energy deposition throughout the chromosphere,…
Analysis of Eruptive Prominence Plasma Parameters' Effects on the \ion{He}{2} 304~Ã Line with Solar Orbiter EUI Observations
Yong Zhang, Nicolas Labrosse, Sargam M. Mulay
An observation of a large prominence on the solar limb took place on February 15, 2022, by the Extreme Ultraviolet Imager (EUI) on board Solar Orbiter. We aim to determine the rang…
Extremely energetic EUV late phase of a pair of C-class flares caused by a non-eruptive sigmoid
Ya Wang, Sargam M. Mulay, Lyndsay Fletcher
The EUV late phase is the second increase of the irradiance of the warm coronal lines during solar flares, and has a crucial impact on the Earth's ionosphere. In this paper, we rep…
Origin of Unusual Composition of 3He-Rich Solar Energetic Particles
R. Bucik, G. M. Mason, S. M. Mulay +3
We examine 3He-rich solar energetic particles (SEPs) detected on 2023 October 24-25 by Solar Orbiter at 0.47 au. The measurements revealed that heavy-ion enhancements increase irre…
Simultaneous Eruption and Shrinkage of Pre-existing Flare Loops during a Subsequent Solar Eruption
Huadong Chen, Lyndsay Fletcher, Guiping Zhou +6
We investigated two consecutive solar eruption events in the solar active region (AR) 12994 at the solar eastern limb on 2022 April 15. We found that the flare loops formed by the…
