Flare Ribbons and the Reconnection (Flux) Rate
http://espos.stream/2026/04/23/Nayak/
Published: April 23, 2026 11:00
Abstract Flare ribbons are a quintessential part of a flare. They are extensively used to understand the overlying reconnection mechanism and overall flaring process. Further, the reconnection rate is a key parameter in the magnetic reconnection process.…
Comparing Solar Structure Detection Methods in SDO/AIA Observations for Onboard Spacecraft Deployment
http://espos.stream/2026/03/26/Gonidakis/
Published: March 26, 2026 11:00
Abstract Recent advances in solar physics increasingly rely on automated identification of coronal structures using machine learning. Yet most studies emphasise scientific performance without evaluating feasibility for onboard deployment to prioritise…
Exploring small-scale coronal loop structures using ultra high resolution observations from the latest Hi-C sounding rocket campaign
http://espos.stream/2026/03/12/Rankin/
Published: March 12, 2026 11:00
Abstract This work takes advantage of new observational data collected by the High-resolution Coronal Imager (Hi-C) at the highest spatial and temporal resolutions available. This most recent Hi-C dataset is the first to make use of the hot 129 Å channel…
Linking Magnetic field Diagnostics with 3D Coronal Mass Ejection Speeds in Solar Active Regions
http://espos.stream/2026/02/26/Gandhi/
Published: February 26, 2026 11:00
Abstract Understanding how magnetic properties of solar active regions influence coronal mass ejection (CME) dynamics is essential for constraining eruption models and improving space-weather prediction. In this work, we investigate the relationship…
Can we anticipate solar flares? Statistical analysis of the Flare Anticipation Index (FAI)
http://espos.stream/2026/02/12/Gonzalez-Prieto/
Published: February 12, 2026 11:00
Abstract Solar flares are the most energetic manifestations of solar activity and can significantly affect Earth’s magnetosphere, ionosphere, and technological systems. Therefore, anticipating these events remains a fundamental challenge in heliophysics.…
Optimising the use of the European Solar Telescope before MCAO: the multi-aperture option
http://espos.stream/2026/01/29/Scharmer/
Published: January 29, 2026 11:00
Abstract We discuss how to optimise the science output of the European Solar Telescope (EST), when used without the wide-field compensation for high-altitude seeing that the EST multi conjugate adaptive optics (MCAO) will offer. This will likely be the…
Understanding the Physics of Small-Scale Hot Coronal Loops
http://espos.stream/2026/01/15/Sola-Viladesau/
Published: January 15, 2026 11:00
Abstract Coronal bright points are ubiquitous, highly energetic events that are often seen accompanying other dynamic and eruptive phenomena in the solar atmosphere. Their large energy output, their similarity to active regions and their connections to…
Wave Period Variability in a Quiescent Solar Prominence
http://espos.stream/2025/12/11/Wisniewska/
Published: December 11, 2025 11:00
Abstract On 26 September 2022, we observed a quiescent solar prominence with Hα imaging spectroscopy using the Solar Dynamics Doppler Imager (SDDI) on the SMART telescope. Unlike earlier works that detected 4- and 15-min oscillations through long-slit, 1D…
Earth’s Ionospheric Response to the Impulsive and Late Phases of Solar Flares
http://espos.stream/2025/11/27/Bekker/
Published: November 27, 2025 11:00
Abstract During a solar flare, fluxes in various lines and continua of the solar spectrum increase, causing enhanced ionisation in the illuminated part of the Earth’s ionosphere and an increase in the total electron content (TEC). The dynamics of TEC…
Connecting Spicules and Propagating Coronal Disturbances Using Radiative MHD Simulations of the Solar Atmosphere
http://espos.stream/2025/11/13/Srivastava/
Published: November 13, 2025 11:00
Abstract Spicules are ubiquitous, small-scale plasma jets that populate the lower solar atmosphere. They are seen prominently in chromospheric observations and also exhibit signatures in the transition region and lower corona. More recently, these highly…
