Abstract

The study of solar activity is a very active area of research due to the increased interest in the relationship between the cycles of sun and weather. The study of solar activity offers the potentiaI for long-range prediction of the behavior of the Sun and associated changes in climate. Many events that initially appeared to be random, for example, global effects such as EI Nino and La Nina could have been predicted well in advance to its commencement. Satellites like SOHO and ACE, monitor the Sun continuously, they are located at Lagrange point 1. However, its greatest potential is restricted to the detection of electromagnetic radiation, especiaIly X-rays, since X-rays propagate in a straight line between the Sun and Earth. However, solar energetic particles are high-energy particles (protons, electrons and ions) from the Sun, with energy ranging from a few keV to hundreds of GeV, originate in processes such as transient solar fiares. They do not traveI in a straight line, but spiraling around the lines of the interplanetary magnetic field. The main objective of this project is the construction of two muon telescopes, cosmic ray secondary particles, which originate in the atmosphere by interactions of protons of high energy, one in Niterói-RJ and the other in Campinas-SP, for the detection and monitoring of transient solar events. Because these places are within and near the central region of the South Atlantic Magnetic Anomaly, the magnetic cutoff rigidity for charged particles from outer space is very low. This allows a sufficient sensitivity to observe solar fiares and other events. The synchronization of these telescopes clocks by GPS, will allow a more detailed study of these events and their correlation with global climatic parameters. Project feasibility is guaranteed by the results of the telescope Tupi. (AU)
