A summary of measurements of cosmic radiation on February 23rd, 1956, performed in Bergen, Norway, is presented. Altogether 7 different components were studied. During the first 16 minutes of the event (03.44-04.00 GMT) the soft and hard intensities lay 350% and 89%, respectively, above their normal values. Our data indicate that the extra radiation from the sun had a greater share of particles with high energies during the peak of the event than later on.
