89 [[The Rise and Fall of The Low Energy Cut Off]]
17 November 2008 by Ewan Dickson and Eduard Kontar
link=The Rise and Fall of The Low Energy Cut Off
Solar hard X-rays tend to have a power-law distribution in energy, implying infinite photon numbers at low energy (a "soft X-ray catastrophe"). Can we observe what limits this behavior?. Click the title to read more.
88 [[SEPs Link not Confirmed]]

link=SEPs Link not Confirmed
The spectral evolution of a solar hard X-ray burst may give a clue to the acceleration of solar energetic particles (SEPs). This RHESSI Science Nugget questions the validity of this predictor.. Click the title to read more.
87 [[The SphinX Instrument on CORONAS-PHOTON]]

An exciting new instrument that will begin observations at an exciting time.. Click the title to read more.
86 [[The Good Guys and the Rascals]]

Solar decimetric radio bursts - but only the good guys - correlate well with RHESSI hard X-rays.. Click the title to read more.
85 [[RHESSI Optical Images]]

RHESSI makes optical images as well as X-ray and gamma-ray ones. This Nugget explains how.. Click the title to read more.
84 [[Flare Plasma Abundances ---- New X-ray Observations]]
2008-09-15 by Brian Dennis and Richard Starr
link=Flare Plasma Abundances ---- New X-ray Observations
MESSENGER is now exploring Mercury. It is also helping RHESSI to understand the solar X-ray spectrum and measure elemental abundances in flares.. Click the title to read more.
83 [[Hard X-rays from a Jet?]]
2008-08-27 by Hazel Miller Bain and Lyndsay Fletcher
link=Hard X-rays from a Jet?
Observations during the rise phase of a M5.4 flare suggests that hard x-rays may be associated with a jet observed by TRACE.. Click the title to read more.
82 [[Are Stellar Flares like Solar Flares?]]
2008-08-11 by Hugh Hudson and Beate Stelzer
link=Are Stellar Flares like Solar Flares?
In this nugget, we explore an extrasolar flare (aka stellar flare). These stellar and solar flares are similar but it is often in subtle differences that we may learn the most.. Click the title to read more.
81 [[The Microflare Height Distribution]]

80 [[The McClymont Jerk]]

The sudden energy release of a flare in the solar atmosphere has many consequences. One of them may be the McClymont Jerk.. Click the title to read more.
