RHESSI Nuggets in October 2020
by Hugh Hudson 25 Oct '20

25 Oct '20

No. 390, “Prediction of Solar Cycle 25”, by Leif SVALGAARD. Now we know how big the next solar maximum will be. No. 391, “Electric Current Neutralization and Eruption”, by Ellis AVALLONE and Xudong SUN. Coronal currents without neutralizing return currents correlate with eruption. No. 392, “Hot Flare Onsets”, by Hugh HUDSON et al. The pre-impulsive temperatures of solar flares are already hot, 10-15 MK. 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 often be found by searching for their SOLyyyy-mm-dd identifier from this home page.
