- Аннотация: The object under study is the fragments of the falling matter during the M 2.5 flare in the NOAA AR 11226 onJune 7, 2011. Observations were carried out with the horizontal solar installation HSFA-2 and the multichannel flarespectrograph MFS (Ondřejov Observatory). The traces of fragments were found in the CaII H, H𝛼, and H𝛽 lines. Afterreducing the line spectra, absorption fluxes were calculated for four moments of time, and a system of equations wassolved for the populations of discrete levels and the ionization state of the hydrogen atom and CaII ion. The source ofradiation was considered in the approximation of a homogeneous layer of heated gas. The gas parameters were selectedin such a way that the observed and theoretical fluxes coincide with an accuracy of better than 5%. Calculations haveshown that the temperature range 𝑇 varies from 7 to 12 thousand K, the column concentration 𝑁 is 1–5 1019 cm−2,and the turbulent speed varies from 6 to 21 km/s.
