- Аннотация: 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 by means of ground-based solar instruments. The eruptive event was characterized by a slowdown in the shock front movement in the first minutes of the development 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, the radial velocities of the fastest features of the exploding prominence were found to be between 200 and 190 km/s. Particular attention was paid to the study of 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 its mass was estimated at 1.8×10^12 g; for the temperature and turbulent velocity, respectively, the values of 7880 K and Vturb = 18.7 km/s were obtained. It should be noted that the detection and measurement of velocities was limited by the capabilities of narrow-band filters and a small wavelength range in most solar devices. 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).
