No. 370: “The Temporal and Spatial Extension of Gamma-ray Emission from the Sun”, by Nat Gopalswamy. Sustained solar γ-rays and solar cosmic rays coincide.
No. 371: “Hot Cusp-Shaped Confined Solar Flare,” by Aaron Hernandez-Perez. A major flare may have a prominent hot cusp without the help of any eruption.… continue to the full article
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.… continue to the full article
