No. 155, Hard X-rays and Sympathy, by Hugh Hudson

A hard X-ray spike elicits a sympathetic response. See

Older Nuggets are available at

http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets
 (the new series), and at
http://sprg.ssl.berkeley.edu/~tohban/nuggets/ (the original series).

We publish these at roughly two-week intervals and welcome
contributions, which should be at least loosely related to RHESSI
science.
