We report the first ever simultaneous burst of PeV energy radiation from a potential source. We recorded 35 showers against an expected background of 17.8, with the KGF air shower array, from Crab during 13:15 - 1600 UT on 23 February 1989, the day on which the Baksan group reported a burst. The EASTOP group also reported excess on the same day. Our data show that the muon content of source showers is the same as that in background showers. All three observations show correlation with the Crab pulsar period. These results suggest that either gamma ray interactions are similar to hadron interactions at PeV energies, or the primaries are neutrinos interacting with a large cross section predicted by some composite models, or a hitherto unknown strongly interacting neutral particle with mass less than 40 MeV/sq c is responsible for the events.
