Announcing RHESSI Science Nugget No. 204, "Implosion and Oscillation," by Paulo Simões and Hugh Hudson. The flare implosion originates in the lower solar atmosphere and creates oscillations visible even in GOES soft X-rays.

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.
