El rol de las características y evolución de las regiones activas solares en la producción de fulguraciones y eyecciones coronales de masa

López Fuentes, M.

Solar events such as flares and coronal mass ejections (CMEs) are the most energetic phenomena affecting interplanetary space in timescales from minutes to a few days. With the main aim of establishing parameters to be used in the prediction of phenomena with potential impact on space weather, there has been in recent years a strong interest in de…

Análisis cinemático de una eyección coronal de masa de 10 a 46 radios solares

Cremades, H.; Balmaceda, L. A.; Di Lorenzo, L.

In this work we perform the three-dimensional reconstruction (3D) of the morphology of a coronal mass ejection (CME), in the range of heliocentric distances of approximately 10 to 46 solar radii. The event occurs on 2 April 2019, and we use observations made by LASCO-C3 aboard the Solar and Heliospheric Observatory (SOHO), SECCHI-COR2 and HI-1 abo…

Comparative study of activity of the near-parabolic orbitcomet C/1977 R1 (Kohler)

de Almeida, A. A.; Sanzovo, G. C.; de Araújo, L. F.

Kohler is considered a case of young, nearly parabolic comet. In this work we deduce, semi-empirically, water and hydroxyl production rates from the photometric observations of this comet taken from the Archive of Photometric Data on Comets and British Astronomical Society archives. Our results are being compared with those obtained from radio obs…
