Description: A small array located near the 80 m/sup 2/ E594 neutrino detector at Fermilab had a two week run. The author makes two comments related to ultra high energy gamma ray physics. The first regards the question of angular resolution from muons. In general, the angle of a muon will not reflect the angle of the shower for reasons which include transverse momentum at production, multiple scattering in the atmosphere, multiple scattering in the detector and detector angular resolution. In multiple muon events, the angle between each muon and the average muon angle samples all of these deviations. Therefore, this is a good measure of the angular resolution of the shower using the muons on an event by event basis. The second comment regards an unusual event from Cygnus X-3.
