It is our pleasure to introduce new Solar Orbiter science nuggets: https://www.cosmos.esa.int/web/solar-orbiter/science-nuggets

SO Nugget #4 “Multi-scale structure and composition of ICME prominence material from the Solar Wind Analyser suite” (R. Dewey and the SWA team)

SO Nugget #5 “Hot X-ray onset observations in solar flares with Solar Orbiter/STIX” (A. F. Battaglia and the STIX team)

SO Nugget #6 “Imaging and spectroscopic observations of extreme-ultraviolet brightenings using EUI and SPICE on board Solar Orbiter” (Z. Huang and the SPICE and EUI teams)

As a reminder, new nuggets will be added on a regular basis, based on input from the entire solar physics community. If you are working on Solar Orbiter data and would like your results to be featured, please contact Yannis Zouganelis (ioannis.zouganelis@esa.int) and Miho Janvier (miho.janvier@esa.int).

No. 446, “A Glasgow geomagnetic observation of a solar flare”, by Hugh HUDSON, John MALONE-LEIGH, Graham WOAN, and Chris OSBORNE. Applying a multi-messenger tool first seen in 1859, the geomagnetic “crochet”.

No. 447, “RHESSI’s Rhe-entry,” by Pascal SAINT-HILAIRE, Albert SHIH, and Hugh HUDSON. RHESSI’s final demise in the Sahara Desert.

No. 448, “Diagnostics of Spatially-Extended Turbulent Acceleration and Transport,” by Morgan STORES. Drilling down into the detailed structure of solar-flare energy release by including turbulence with particle acceleration.

No. 449, “Did a Solar Flare Accelerate all the Ambient Electrons in the Coronal Acceleration Region?” by Gordon EMSLIE, Eduard KONTAR, Galina MOTORINA, and Brian DENNIS. Considering SOL2017-09-10, probably not.

We welcome almost any contribution to the RHESSI Nuggets. The topic may wander some distance away from specifically RHESSI results if it is generally interesting. See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets for these and others. Comments about specific flares can often be found by searching for their SOLyyyy-mm-dd identifier from this home page.… continue to the full article

Dear colleagues,

It is our pleasure to introduce the Solar Orbiter science nuggets, showcasing research using Solar Orbiter data:
https://www.cosmos.esa.int/web/solar-orbiter/science-nuggets

The first three nuggets are online now, and new ones will be added on a regular basis, based on input from the entire solar physics community. If you are working on Solar Orbiter data and would like your results to be featured as a future Solar Orbiter science nugget, please contact Yannis Zouganelis (ioannis.zouganelis@esa.int) and Miho Janvier (miho.janvier@esa.int).

Read the first nuggets:

“Radial dependence of the peak intensity of solar energetic electron events in the inner heliosphere” (L. Rodriguez, A. Kollhoff and the EPD team) (url: https://www.cosmos.esa.int/web/solar-orbiter/science-nuggets/radial-dependence-of-the-peak-intensity-of-solar-energetic-electron-events-in-the-inner-heliosphere)
