In this thesis we present the first results of a study in progress about a possible association among excess and deficit of muons observed at sea level by the Tupi teles-cope and transient events originated for the solar activity. An analysis of the observed phenomena using satellite data such as GOES and ACE show that the muons excess in the majority of the cases has potential for an association with solar flares of small scale and the muons deficit presents an anti-correlation with the arrival of solar parti- cles in the keV energy region. The good performance of the Tupi telescope is partly a consequence of the high counting rate of the acquisition data system and that arrives up to 100 kHz and partly due to the tracking system of the telescope and that allows that the telescope s axis points close to the lines of the interplanetary magnetic field. Here it is also discussed an origin of the events without an apparent association with flares and energetic solar particles.
