The most energetic X-class flares on 2003 Nov. 2 and Nov. 4 were observed at Helio Research at multiple wavelengths around the Hydrogen alpha line. The flares were recorded in 0.5 Angstrom steps in the range of -2 to +2 Angstroms using a tunable filter of 1 Angstrom half-width. The tunable filter was employed in the Helio Research 25 cm aperture telescope with a field of view limited to 10 X 10 arc min.
The flare of Nov 2 was observed entirely against the solar disk. The images reveal the brightest parts of the extended flare. The time-lapse movies of these images show how the bright core of the chromospheric part of the flare spreads across each of 3 large sunspot umbrae of the associated active region.
The Nov 4 flare was observed primarily as complex system loops above limb with an occulting disk blocking most of the solar disk. These sets of images show the development and evolution of the flare loop system. Doppler motions in the range of - 90 to + 90 km/sec within the loops are well revealed in these time-lapse series at 9 wavelengths shown as time-lapse movies.
The observations and analyses are supported under NASA grant NAG5-10852 and are available for correlative studies with data sets from other observatories.
