Evidence of the radio-quiet hard X-ray precursor of the 13 December 2006 solar flare

Zimovets, I. V.; Struminsky, A. B.; Gros, M.

We report multi-wavelength investigation of the pre-impulsive phase of the 13 December 2006 X-class solar flare. We use hard X-ray data from the anticoincidence system of spectrometer onboard INTEGRAL (ACS) jointly with soft X-ray data from the GOES-12 and Hinode satellites. Radio data are from Nobeyama and Learmonth solar observatories and from t…

On-disk signatures of eruptive activity from the Hinode mission

Harra, Louise K.

On-disk signatures of eruptive activity have been investigated for many years. These include filament eruptions, flares, coronal waves and dimmings. The Hinode mission is providing a new perspective on eruptive activity on the Sun and its linkage to the Earth. Despite being in a period of solar minimum since the launch of Hinode in September 2006,…
