[69.03] RHESSI imaging and flare analysis using MEM-Sato

J. Sato (MSU)

RHESSI was successfully launched in this February. It is a first instrument to observe solar flare hard X-rays with its high spatial and spectral resolutions. I developed an imaging algorithm for RHESSI using Maximum Entropy Method called as MEM-Sato. The synthesized image will achieve high dynamic range ( about 100:1) by the sufficient UV data points. After the RHESSI launch, various solar flares were observed and MEM-Sato algorithm was revised with some minor modifications. As a result, we obtain a dramatic image of solar flares as expected by the RHESSI's capability. I present some results of RHESSI data analysis using MEM-Sato algorithm.
