The data presented recently by Lande, et. al. has to do with the time structure of the antineutrinos apparently received from an extraterrestrial source. At least four microsecond bursts separated by 0.640, 0.968, and 0.928 ms. were observed. If these bursts originated in an isotropically emitting source near the galactic center, then about 3 x 10 to the 52d power ergs is contained in each ms burst. It is shown that the approximately millisecond period is characteristic of matter at high density and the microsecond burst width is characteristic of an extremely temperature- and density-dependent emission mechanism and a mean free path (approximately 500,000 cm) characteristic of high-energy antineutrinos in dense matter. The energy per pulse and number of pulses is what would be expected in the gravitational collapse of a white dwarf core to a radially pulsating hot neutron star.
