114. Hidden Coronal Loop Strands within Hi-C 2.1 Data

Author: Thomas Williams and Robert W. Walsh at the University of Central Lancashire. << previous nugget — next nugget >> Introduction Observational investigations of coronal loop structure have been undertaken since the 1940s [1]; however, due to insufficient spatial resolution of current and previous instrumentation, the definitive widths of these fundamental structures have not been …

110. Flare/CME Cartoons

Author: Hugh Hudson, Nicolina Chrysaphi, and Norman Gray at the University of Glasgow. << previous nugget — next nugget >> Introduction A “Grand Archive of Solar Flare Cartoons” has long existed on the Web [1], but without updates within the past decade because of the unfortunate loss of a password, and because the original quite …

109. Kink oscillations of sigmoid coronal loops

Author: Norbert Magyar and Valery M. Nakariakov at the University of Warwick. << previous nugget — next nugget >> Introduction In solar physics, coronal loops have long been in the spotlight. As building blocks of the closed solar corona, understanding their structure and evolution is akin to understanding the coronal heating problem. Moreover, oscillations detected …
