Announcing a new RHESSI Science Nugget
by Hugh Hudson 07 Aug '13

07 Aug '13

No. 205, "Acceleration-region Densities," by Sa"m Krucker and Marina Battaglia. Independent constraints on the densities of ions and non-thermal electrons point to bulk acceleration. See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/Acceleration-region_Den… 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.

by Hugh Hudson 29 Jul '13

29 Jul '13

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. http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/Implosion_and_Oscillati… 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).

Senior Review Ratings and Recomendations
by Dennis, Brian R. (GSFC-6710) 05 Jul '13

05 Jul '13

RHESSI was given an excellent rating by the Heliophysics Senior Review panel for both "overall scientific merit of the proposed extended mission" and for "Value to the Heliophysics System Observatory." The Panel recommends "the continued operation of the RHESSI extended mission," and states in its report that "RHESSI plays a unique role within the HSO, enabling system-wide studies of energy release and particle acceleration in flares/CMEs and their effects on the interplanetary medium, magnetosphere, and ITM." The full report will be put on line at http://hesperia.gsfc.nasa.gov/rhessi2/home/mission/documents/ as soon as we receive a corrected version from NASA HQ. Säm Krucker has been officially appointed by NASA as the RHESSI PI. Brian Brian R. Dennis Solar Physics Laboratory, Code 671 Goddard Space Flight Center Greenbelt, MD 20771 301-286-7983 brian.r.dennis(a)nasa.gov
