Abstract
We have analyzed muons and multimuons detected in the Fréjus underground nucleon decay detector between February 1984 and June 1986. No excess events are observed in the direction of Cygnus X-3, which yields a 90 % confidence level upper flux limit of 0.7 10-12 cm-2 s-1, for an average rock overburden of 5000 hg cm-2 corresponding to energies > 3 TeV. Using the 4.79 hour periodicity of Cygnus X-3, no signal is found in any phase interval.
