RHESSI Science Nuggets in January 2020
by Hugh Hudson 23 Jan '20

23 Jan '20

No. 368: “Remembering John Brown,” by Alec MacKinnon. We mourn the loss of one of RHESSI’s leaders. No. 369: “A PSP Perihelion,” by Jessie Duncan and Hugh Hudson. At this very moment, the Parker Solar Probe is entering its fourth and deepest-yet perihelion passage We welcome contributions to the RHESSI Nuggets, and the topics may wander some distance away from specifically RHESSI results if they are generally interesting. See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets for these and others. Comments about specific flares can be found by searching for their SOLyyyy-mm-dd identifier from this home page.

RHESSI Nuggets in December, 2019
by Hugh Hudson 31 Dec '19

31 Dec '19

Farewell to 2019! There were 25 new Nuggets in all during the year, thanks to as many contributors. The new ones in December were: No. 365, “Spectropolarimetric Insight into Plasma-Sheet Dynamics of a Solar Flare,” by Ryan French. The CoMP polarization patterns in SOL2017-09-10 are extremely promising. No. 366, “Cosmic Rays over the Rainbow Bridge,” by Hugh Hudson and Alec MacKinnon. Galactic (and solar) cosmic range plummet into the Sun. No. 367, “A Global Survey of EUV Coronal Power Spectra,” by Karl Battams. Time-series maps of imaged power spectra from an AIA pipeline. Please see http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets for access to the full list, with search capability. We publish these at roughly two-week intervals and welcome contributions, which should be related, at least loosely, to RHESSI science. At the time of writing another new-cycle region is on the disk, although it has lost its spots already. So… Happy New Year to all!
