Two new RHESSI Science NuggetsApril 11, 2018, from Hugh Hudson
No. 320, “Blue-wing enhancement of the Mg II h and k lines in a flare”, by Akiko TEI. Flare loops may involve a cool upflow preceding the hot evaporation flow.
No. 321, “A sunspot from Cycle 25 for sure”, by Tomek Mrozek and Hugh Hudson. YES! Cycle 25 is here already!
See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets listing the current series, 2008-present, and http://sprg.ssl.berkeley.edu/~tohban/nuggets/ for the original series, 2005-2008. We publish these at roughly two-week intervals and welcome contributions, which should be related, at least loosely, to RHESSI science.
