Fine-scale flare structures and their energetic implications from short-exposure extreme-ultraviolet imaging
Laura A. Hayes, Hannah Collier, Säm Krucker +5
To capture the brightest and most rapidly evolving phases of solar flares, the Major Flare Solar Orbiter Observing Plan employed a dedicated short-exposure mode for the High Resolu…
Decay Length of Slow Magnetoacoustic Waves in the Solar Corona using SDO/AIA and SolO/EUI
R. L. Meadowcroft, N. Narang, D. Berghmans +2
Slow magnetoacoustic waves have been observed in the solar corona for decades; yet, existing theories do not fully explain the wide range of observed decay lengths, and measurement…
Fast and periodic propagating disturbances along coronal loops detected with EUI on board Solar Orbiter
A. Dolliou, S. Mandal, K. Barczynski +9
Recent high-resolution observations from the Solar Orbiter mission can help detect the indirect signatures of heating at the smallest scales. In this work we measure the properties…
A universal scaling between damping time and period of quasi-periodic pulsations from solar EUV brightenings to X-ray stellar flares
Daye Lim, Tom Van Doorsselaere, Valery M. Nakariakov +5
Recent high spatial and temporal resolution extreme-ultraviolet (EUV) imaging observations have revealed that quasi-periodic pulsations (QPPs), a ubiquitous signature of impulsive…
A Point-Spread Function for the Extreme Ultraviolet High-Resolution Imager on board Solar Orbiter
Stefan J. Hofmeister, Emil Kraaikamp, Sergei Shestov +7
We present the point-spread function (PSF) of the Extreme Ultraviolet High-Resolution Imager (HRIEUV) onboard Solar Orbiter, which observes the Sun at 174 Angstrom. This PSF provid…
Small-Scale and Transient EUV Kernels in Solar Flare Ribbons
Hannah Collier, Säm Krucker, Laura A. Hayes +3
Flare ribbons form when energy released by coronal magnetic reconnection is deposited in the low solar atmosphere, so by studying the dynamics of flare ribbons, one obtains an indi…
Eruption-Related Ultraviolet Irradiance Enhancements Associated with Flares
Luke Majury, Marie Dominique, Ryan Milligan +3
Large solar flares (GOES M-class or higher) are usually associated with eruptions of material. However, when considering flare irradiance enhancements and dynamics such as chromosp…
A multi-viewpoint comparison of the velocity field of coronal propagating disturbances
Nina Stankovic, Huw Morgan, Marilena Mierla +3
Small-scale propagating disturbances (PD) are ubiquitous in the solar corona. Time-Normalised Optical Flow (TNOF) is a method developed for mapping PD velocity fields in time serie…
Accessing the fine temporal scale of EUV brightenings and their quasi-periodic pulsations: 1 second cadence observations by Solar Orbiter/EUI
Daye Lim, Tom Van Doorsselaere, Nancy Narang +7
Small scale extreme ultraviolet (EUV) transient brightenings are observationally abundant and critically important to investigate. Determining whether they share the same physical…
Buildup, Explosion, and Untwisting of a Solar Active Region Jet Observed with Solar Orbiter, IRIS, and SDO
Navdeep K. Panesar, Alphonse C. Sterling, Ronald L. Moore +6
We present detailed analysis of an active region coronal jet accompanying a minifilament eruption that is fully captured and well-resolved in high spatial resolution 174A coronal i…
Co-existence of longitudinal and transverse oscillations in polar plumes observed with Solar Orbiter/EUI
Upasna Baweja, Vaibhav Pant, S. Krishna Prasad +6
Magnetohydrodynamic (MHD) waves play a key role in heating the solar corona and driving the solar wind. Recent observations have shown the presence of slow magneto-acoustic and Alf…
Solar Orbiter's 2024 Major Flare Campaigns: An Overview
Daniel F. Ryan, Laura A. Hayes, Hannah Collier +17
Solar Orbiter conducted a series of flare-optimised observing campaigns in 2024 utilising the Major Flare Solar Orbiter Observing Plan (SOOP). Dedicated observations were performed…
