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

Abstract

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 aboard the Solar-Terrestrial Relations Observatory Ahead (STEREO-}) and WISPR-I aboard the Parker Solar Probe (PSP). From simultaneous observations of LASCO-C3 and COR2-A, we determined the three-dimensional position of the CME and interconnected these measurements with those obtained by PSP. We then calculate the heliospheric distance from the center of the CME and the radius of the CME. In addition, we estimate the speed and acceleration of both propagation and expansion of the CME.
