by Eduard Kontar 29 Jan '19

29 Jan '19

Coronal Mass Ejection-driven Type II solar radio burst structure with LOFAR and radio-wave scattering by Nicolina Chrysaphi et al.* http://cesra.net/?p=2109 Synthetic Radio Imaging in Quiet and Eruptive Solar Cases by S. P. Moschou et. al.* http://cesra.net/?p=2101 Simulation of Focusing Effect of Traveling Ionospheric Disturbances on Meter-Decameter Solar Dynamic Spectra by A. Koval et al* http://cesra.net/?p=2090 --- CESRA Highlights of Solar Radio Physics, aka CESRA Nuggets, are short communications written in language accessible to a non-expert in the specific area and designed to keep solar and heliophysics communities informed and up-to-date about current research. The highlights can be followed, discussed, commented and shared via http://www.facebook.com/solarcesra/ and http://twitter.com/CESRA_community

RHESSI Science Nuggets in January 2019
by Hugh Hudson 29 Jan '19

29 Jan '19

No. 343, “Short-period Waves”, by Sijie YU and Bin CHEN. New decimetric imaging spectroscopy suggests Alfvenic energy transport in solar flares. No. 342, “The Interesting RHESSI/SAS Archive”, by Hugh Hudson and Martin Fivian. The full mission database shows RHESSI to have been very stable geometrically. Although RHESSI is off the air, results continue to appear. We welcome contributions on a variety of solar research areas, especially those involving RHESSI, and will welcome more for at least the duration of 2019. See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets, listing the current series, 2008-present, and http://sprg.ssl.berkeley.edu/~tohban/nuggets/ for the original series, 2005-2008.

Announcing RHESSI Nuggets
by Hugh Hudson 14 Jan '19

14 Jan '19

No. 342, the first of 2019: “The Interesting RHESSI/SAS Archive”, by Hugh Hudson and Martin Fivian. The full mission database shows RHESSI to have been very stable geometrically. Three Nuggets in December 2018: No. 341, “Homologous White Light Solar Flares”, by Paolo Roman and Abouazza Elmhamdi. Homologous white-light flares, in rapid succession, and coronal null points. No. 340, “The Flight of FOXSI-3”, by Lindsay Glesener and Noriyuki Narukage. Single-photon counting and direct focusing across hard and soft X-ray energies. No. 339, “Stellar Flares and Starspots”, by Lauren Doyle. Stellar flares don’t spatially match their starspots. In 2018 we had 28 Nuggets, ranging over a wide variety of HXR-themed solar research matters, and welcome more for 2019. See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets, listing the current series, 2008-present, and http://sprg.ssl.berkeley.edu/~tohban/nuggets/ for the original series, 2005-2008. We publish these at roughly two-week intervals and welcome contributions, which should be related, at least loosely, to RHESSI science.
