Analysis of two active prominences

We discuss the observations of two eruptive prominences, and the formation of condensations during the phenomena. The density and intensity variations of the condensations are analyzed spectroscopically in one of the events. Some hypotheses about the magnetic field configuration have been used in order to explain the observational data. The paper in full will be published in Solar Physics.Asociación Argentina de Astronomí

Macroscopic motions in prominences I, the prominence of 26th March, 1971

Macroscopic velocity fields have been studied in a solar prominence. The spectra and monochromatic images were analysed, and the existence of a contracting motion, possibly due to a pinch effect, is discussed. A helical shape of the prominence is proposed.

The loop prominence of May 13, 1971 and its associated effects

A study is presented about the formation of a loop prominence system (LPS) on May 13, 1971. The development of the phenomenon in found the follow the model of Jefferies and Orrall, and was associated with small radio bursts and several kind SID. From the spectral analysis a temperature of 13200 K has been deduced and a density of hydrogen atoms n(H) = 10¹⁰ cm⁻⁸ estimated. The existence of inclined emissions probably produced by rotatory motions is discussed. From the radio-data analysis it was inferred that an impulsive and a thermal component were present, the length of the emitting plasma cloud was found to be about 56000 Km. The LPS appeared, in accordance to previous results, in a región producing proton fiares. The paper in full will be published in Solar Physics.Asociación Argentina de Astronomí
