RHESSI and H study of the X4 Flare of 3 Nov 2003 Veronig1, M. Temmer1, B. Vršnak2, J. Magdalenić2 1 University of Graz, Austria 2 University of Zagreb, Croatia

H image time series (Kanzelhöhe Solar Observatory) 09:00 UT – 12:50 UT

H difference images during impulsive phase (09:48 – 10:00 UT) Diffuse Moreton wave

RHESSI CLEAN images at different energies

RHESSI 15-20 keV images: Loop-top source

Evolution of RHESSI footpoints and loop top source Footpoints: 70-100 keV Loop top: 20-25 keV

RHESSI (09:46-10:01 UT) and H (10:00-12:00 UT) loop top source evolution

Spectral hardness via flux ratios: (70 – 100 keV) / (100 – 200 keV) (12 – 15 keV) / (25 – 30 keV)

RHESSI 20-25 keV images during HXR onset Above loop top source?? ejection??
