Our estimates show that fluctuations of the di-quark gap may strongly affect some of thermodynamic quantities even far below and above the critical temperature. If the critical temperature $T_c$ of the di-quark phase transition were rather high ($\gsim (50÷70)$ MeV) one could expect a manifestation of fluctuations of the di-quark gap in the course of heavy ion collisions (above $T_c$). For $T_c \sim 50 $MeV color superconducting fluctuations may also affect an initial stage of the hybrid star evolution.19 p. For proc.
