CESRA Highlights of Solar Radio Physics, aka CESRA Nuggets, are short communications written in language accessible to a non-expert in the specific area and designed to keep solar and heliophysics communities informed and up-to-date about current research.… continue to the full article
No. 351, “The Cosmic-Ray Shadow and Coronal Magnetism”, by Frederik Tenholt: Measuring the coronal magnetic field in Antarctica.
No. 350, “Kristian Birkeland”, by Hugh Hudson and Lyndsay Fletcher: Space weather a century ago.
See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets .
We publish these at roughly two-week intervals and welcome contributions,
which should be related, at least loosely, to RHESSI science.… continue to the full article
