RHESSI Science Nugget No 300

May 15, 2017, from Hugh Hudson

“A Lasso Model for Solar Gamma-Ray Events,” by Hugh Hudson. Retracting large-scale coronal magnetic fields can trap SEP particles to support a long-duration gamma-ray event.

See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets

listing the current series, 2008-present, and


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.
