AB: The effects of electric thunderstorms on the electromagnetic and muon components of the cosmic ray secondary flux were studied during severe storms in 2004 and part of 2005 analyzing the variations of the counting rates shown in the upper and lower scintillators of the muon telescope installed in Mexico City. Results show that for positive configurations of the electric field soft component particles show an increase of flux that can be interpreted as particle acceleration. For the hard component the inverse effect is observed, that is a decrease in the counting rates for positive electric field storms. These results are in agreement with those obtained by Khaerdinov et al (1 and 2).
