New RHESSI Science Nuggets
by Hugh Hudson 11 Feb '23

11 Feb '23

http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets No. 440, "Rapid variations of Si IV spectra in a flare observed by IRIS at a sub-second cadence,” by Juraj LÖRINČIK. Transition-region lines in a flare have a Doppler component revealing quasi-periodic pulsations. No. 441, "A slow HOPE with microwave context,” by Hugh HUDSON. A new microwave facility at Chashan Observatory, and a prototypical Hot Onset Precursor Event. No. 442, "A possible coronal magnetic flare precursor,’ by Enrico LANDI. Novel measurements of the coronal magnetic field may help with flare prediction. No. 443, "Hard X-ray Pulsations via Gaussian Decomposition,” by Hannah COLLIER and Laura HAYES. Flare hard X-ray time variations decomposed objectively We welcome contributions to the RHESSI Nuggets, and the topics may wander some distance away from specifically RHESSI results if they are generally interesting. See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets for these and others. Comments about specific flares can often be found by searching for their SOLyyyy-mm-dd identifier from this home page.
