  The angular clustering of 5 Ultrahigh Energy Cosmic Rays (UHECRs) in the
combined published AGASA-HiRes data has a probability of ~ 2 10^-3 of occurring
by chance. A first analysis of the implications of the event energies and
angular spreading is presented, which is applicable if the source is close
enough that GZK losses can be ignored. Under this assumption, the observed
energies of the events in this cluster favor a bursting rather than
continuously emitting source, with the events emitted on a time scale short
compared with 300 D_Mpc years. Assuming the UHECRs experience many incoherent
small magnetic deflections enroute from source to Earth, the arrival direction
distribution allows estimation that < B^2 lambda > D ~ 7.7 nG^2 Mpc^2, where
lambda is the coherence length of the field and D is the source distance. If
the spectrum at the source ~ E^{-2}, the total isotropic equivalent energy
emitted in UHECRs is > 10^43 D_Mpc^3 ergs.
