The C
60
fullerite has been Ca-intercalated under high pressure up to 240 kbar induced by a pressure shock wave. Magnetometric measurements have revealed superconductivity of the as-prepared sample at 9.9 K. The sample relaxed under normal conditions in the helium atmosphere has exhibited traces of superconductivity with the onset at T = 30 K.
