We hope to see you all for this informal 1-day meeting that brings together researchers from CU, HAO, LASP, NOAA, NSO, NWRA, and SwRI as well as out-of-town visitors to give an overview of solar research being accomplished at local institutes and to discuss current progress on solar instrumentation, observations, and models.
International UCoMP Users Workshop
HAO director Holly Gilbert comments: "There was great energy around the UCoMP Users Workshop last week, with many visitors coming from around the world to participate. Thanks to those who made it a success, including many early career folks!" The first-ever UCoMP Data User’s Workshop was held the week of August 29 and was a great success. The purpose was to introduce UCoMP to the community and to organize working groups to collaborate on UCoMP first results to be published in a topical issue of Solar Physics.
COSMOrama's new video — "My Corona"!
The upcoming solar eclipses and excitement of COSMO development have us so giddy that we broke into song (literally). We invite you to watch the result!
Latest Research Highlights
The Problem of Coronal Heating
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.
Magnetic fields and plasma heating in the Sun’s atmosphere
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.
Advances in solar telescopes
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.
