A large scatter in the data on the light curve of T CrB is explained by the flickering activity of the system. The data of April 1996 have a falling trend, and this can be a part of downward branch of a long-term and energetically powerful flare. The estimated energy (2x10³⁵ J) and the duration of this event were compared with theoretical assumptions based on the three physical scenarios, which can be flickering sources. The dissipation of magnetic loops and the existence of the turbulent eddies are energetically deficient, but these scenarios are real in the case of less powerful flares. The real explanation could be instability of the secondary component and the variable mass transfer rate through the Lagrangian point.
