Abstract
At the MSU EAS array the temporal distributions of particles in extensive air showers (EAS) with energies greater than 1014 eV were studied. Delayed particles were registered in 3.5% of EAS. The flash in the frequency rate of registration of delayed particles from 1986 to 1990 with a maximum of the registration frequency in 1987 and the fine structure of which at the decline of the flash, consisted of a series of bursts of quasi-periodic fading oscillations with an oscillation period of approximately 4 days and a burst duration of about 32 days, is discussed. At the same time, the EAS frequency registration rate in limits of statistical errors was unchanged.
