Announcing a new RHESSI Science Nugget

No. 206, "Negative Microwave Bursts," by Victor Grechnev and Hugh Hudson. Negative microwave bursts happen, in association with flares and with "Hyder flares," and modern instrumentation makes them very interesting again; See

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

Older Nuggets are available at http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets (the current series, 2008-present), and at http://sprg.ssl.berkeley.edu/~tohban/nuggets/ (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.
