Abstract
We have observed underground cosmic-ray muons, corresponding to a secondary flux of 7×10-11 cm-2 s-1, at a depth of 1800 m water equivalent, which appear to be initiated by Cygnus X-3. This identification is based on both direction and phase coherence. The existence of such secondary muons conflicts with the current understanding of photon cascades and/or the nature and location of Cygnus X-3.
