Two new RHESSI Science Nuggets
by Hugh Hudson 12 May '20

12 May '20

No. 378, “Rejuvenating Solar Flare Termination Shocks as Particle Accelerators,” by Bin CHEN: At last, clear evidence for a long-predicted phenomenon. No. 379, “Quasi-periodic pulsations as indicators of oscillatory processes in solar flare,” by Elena Kupriyanova et al.: Many, many QPPs 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.
