Research Highlights

This fascinating memoir covers the scientific life of Dr. Andrew Skumanich, starting with his family’s background and their immigration to the US. It continues with Andy's childhood, early education, his influential introduction to science, and finally his illuminating career, which started at Los Alamos Scientific Laboratory in the 1950s and then continued in solar physics at the High Altitude Observatory (National Center for Atmospheric Research).

X. Liu, H. Tian, T. Toeroek, S. Gibson, Z. Yang, W. Li, and T. Samanta show results that the COronal Solar Magnetism Observatory (COSMO) Large Coronagraph (LC) can provide magnetic field measurements of CME progenitors with a high spatial resolution (2′′ pixels). By using a worse resolution (6′′ pixels), the COSMO LC observation may also be used to qualitatively study the evolution of magnetic field during the CME eruption.

This new book, by Phil Judge et al., offers a critical overview of the field of research, including a dive into methodologies to understand the nature of this recalcitrant problem. Armed with an up-to-date understanding of theory, instrumentation, and the developing field of machine learning, the authors offer suggestions for new, stronger methodologies aimed to generate measurable progress.

Philip Judge, Lucia Klient, Roberto Casini, Alfred de Wijn, Tom Schad, and Ali Tritschler uniquely connect magnetic fields threading the chromosphere to the overlying corona and other heated plasmas. They found no correlations between heated plasma and properties of chromospheric magnetic fields on scales below supergranules. 

Holly Gilbert notes that sunspot observations have been recorded for over 400 years, and eclipses were first documented thousands of years ago. Although the Sun is no longer a complete mystery, the way we observe it continues to develop, as continued technological advances uncover new mysteries for future generations to solve.

Michael Wiltberger et al. present a method for publishing and sharing high performance compute (HPC) code and results in a ready-to-use interactive environment with the explicit goal to lower the entrance barrier to HPC. They call such an environment an OpenScienceLab (OSL).

Kun Wu, Liying Qian, Wenbin Wang, Xuguang Cai, Joseph M. Mclnerney used the Whole Atmosphere Community Climate Model (WACCM-X) to simulate the EIA structures during the storm on November 3 to 4, 2021 observed by the Global-scale Observations of the Limb and Disk (GOLD) mission

K. Alielden, D.MacTaggart, Q. Ming, C. Prior and B. Raphaldini present ARTop (Active Region Topology), a package that allows researchers to calculate the fluxes of topological quantitiesbased on solar magnetograms. In addition to this, ARTop also allows for the efficient analysis of these quantities in both two-dimensional maps and time series. ARTop calculates the fluxes of magnetic helicity and magnetic winding, together with particular decompositions of these quantities.

Breno Raphaldini, et. al. observed wavenumber-frequency spectrum of tropical tropospheric disturbances (Wheeler-Kiladis diagram) helping to bridge the gap between observations and the linear theory of equatorial waves.
