Evolución de una protuberancia observada por el HASTA
Abstract
Prominence eruptions are one of the most spectacular manifestations of solar activity; in addition to flares and coronal mass ejections. Both filaments and prominences are chromospheric material suspended in the corona by the magnetic field. Hence their importance as tracers of field ejections. Some parts of their magnetic structure are not well understood; especially with regard to the loss of stability. On 06 December 2010 the H-Alpha Telescope for Argentina (HASTA) observed a prominence in the eastern solar limb including when part of it was ejected. In this paper the evolution of the filament is analyzed; its structure before and after the eruption; determining parameters that characterize it from HASTA data. FULL TEXT IN SPANISH
