Abstract

We present the results of the analysis of the observational data for the eruptive event of June 7, 2011 obtained both on spacecraft (SDO, LASCO) and using ground-based solar instruments. The event was characterized by deceleration of the shock front during the first minutes of the evolution from 1150 to 710 km/s. According to the LASCO data, the velocity of the coronal mass ejection (CME) on time scales of more than an hour did not exceed 285 km/s. According to the spectral observations of the ground-based instrument, we found the radial velocities of the fastest features of the exploding prominence to be between 200 and 190 km/s. We paid special attention to studying the physical characteristics of a blob—a separate drop of coronal rain that accompanied the event. The line-of-sight velocity of the blob increased in 5 min from 207 to 263 km/s, its diameter was 5900 km, and the estimated mass was 1.8 × 1012 g; the values of temperature and turbulent velocity of 7880 K and Vturb = 18.7 km/s were obtained,correspondingly. We should note that the finding and measurement of velocities were limited by the capabilities of narrow-band filters and a small wavelength range in most solar instruments. This paper is based on the report made at the conference “Ideas of S.B. Pikelner and S.A. Kaplan and Modern Astrophysics” (Sternberg Astronomical Institute, Moscow State University, February 8–12, 2021).
