by Hugh Hudson 21 Jan '13

21 Jan '13

RHESSI Science Nugget No. 192, "Kappa Distribution" (by Mitsuo Oka, Berkeley) - A simpler function fits both thermal and non-thermal hard X-ray components simultaneously. See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/Kappa_Distribution 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.

Announcing two RHESSI Science Nuggets
by Hugh Hudson 28 Dec '12

28 Dec '12

A New Year's special: two new RHESSI Science Nuggets: No. 189, "FOXSI Success" (Lindsey Glesener and Sa"m Krucker) - the FOXSI rocket soared, and right on schedule a B-class flare was detected. No. 190, "Flare Productivity" (Hugh Hudson and Lyndsay Fletcher) - the number of flares per active region fluctuated oddly in 2004-2005, and the RHESSI flare observations help to track such statistical features. 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).
