Hinode Flare Catalogue

Catalogue of 1{3 Ghz Solar Flare Radio Emission

Solar ares frequently radiate in the 1{3 GHz range, the lowest frequency microwaves, but not much is known about the spectral shape of these emissions. We present a catalogue of selected bursts observed with a new spectrometer at ETH Zurich in the years 1989{1993. The original data set includes 268 events of various types. Featureless broadband continua generally attributed to gyrosynchrotron e...

Hinode Observations of Vector Magnetic Field Change Associated with a Flare on 2006 December 13

Continuous observations of a flare productive active region 10930 were successfully carried out with the Solar Optical Telescope onboard the Hinode spacecraft during 2007 December 6 to 19. We focus on the evolution of photospheric magnetic fields in this active region, and magnetic field properties at the site of the X3.4 class flare, using a time series of vector field maps with high spatial r...

Flare Ribbons Observed with G-band and Fe I 6302Å Filters of the Solar Optical Telescope on Board Hinode

The Solar Optical Telescope (SOT) on board Hinode satellite observed an X3.4 class flare on 2006 December 13. Typical two-ribbon structure was observed, not only in the chromospheric Ca II H line but also in G-band and Fe I 6302 Å line. The high-resolution, seeing-free images achieved by SOT revealed, for the first time, the sub-arcsec fine structures of the “white light” flare. The G-band flar...

Network Loop Oscillations with EIS/Hinode

We analyze a time sequence of He II 256.32 Å images obtained with EIS/Hinode, sampling a small magnetic loop in magnetic network. Wavelet analysis indicates 11-min periodicity close to the loop apex. We interprete this oscillation as forcing through upward leakage by the fundamental acoustic eigenmode of the underlying field-free cavity. The observed loop length corresponds to the value predict...
