Automated detection of coronaL MAss ejecta origiNs for space weather AppliCations (ALMANAC)
Thomas Williams, Huw Morgan
Alerts of potentially hazardous coronal mass ejections (CME) are based on the detection of rapid changes in remote observations of the solar atmosphere. This paper presents a metho…
A solar-cycle study of coronal rotation: large variations, rapid changes, and implications for solar wind models
Liam T. Edwards, David Kuridze, Thomas Williams +1
Information on the rotation rate of the corona, and its variation over latitude and solar cycle, is valuable for making global connections between the corona and the Sun, for globa…
The cross-sectional shape and height expansion of coronal loops: High-resolution Coronal Imager (Hi-C) analysis of AR 12712
Thomas Williams, Robert W. Walsh, Huw Morgan
Coronal loop observations have existed for many decades yet the precise shape of these fundamental coronal structures is still widely debated since the discovery that they appear t…
Multi-Stranded Coronal Loops: Quantifying Strand Number and Heating Frequency from Simulated Solar Dynamics Observatory (SDO) Atmospheric Imaging Assembly (AIA) Observations
Thomas Williams, Robert W. Walsh, Stephane Regnier +1
Coronal loops form the basic building blocks of the magnetically closed solar corona yet much is still to be determined concerning their possible fine-scale structuring and the rat…
Evidence for and Analysis of Multiple Hidden Coronal Strands in Cross-Sectional Emission Profiles: Further Results from NASA's High-resolution Solar Coronal Imager
Thomas Williams, Robert W. Walsh, Hardi Peter +1
Previous work utilising NASA's High-resolution Coronal Imager (Hi-C 2.1) 17.2 nm observations revealed that, even at the increased spatial scales available in the data-set, there m…
Is the High-Resolution Coronal Imager Resolving Coronal Strands? Results from AR 12712
Thomas Williams, Robert W. Walsh, Amy R. Winebarger +14
Following the success of the first mission, the High-Resolution Coronal Imager (Hi-C) was launched for a third time (Hi-C 2.1) on 29th May 2018 from the White Sands Missile Range,…
