RHESSI Nuggets in February 2022
by Hugh Hudson 26 Feb '22

26 Feb '22

http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets No. 426, “A demonstration of STIX hard X-ray imaging spectroscopy capabilities for an X-class flare (SOL2021-10-28),” by Andrea BATTAGLIA, Hannah COLLIER, and Säm KRUCKER. STIX imaging of an X-class flare marks its successful beginning. No. 427, “Probing chromospheric current sheets using SST and ALMA co-observations,” by Joäo da SILVA SANTOS. Emerginc magnetic flux appears in ALMA images to be reflecting coronal current sheets. 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.
