Abstract

Because of the importance of the impact of geoeffectiveshocks phenomena in Earth's magnetosphere and its impact on it, are of great interest the study of all solar phenomena that influence the Earth's climate, in this case the coronal ejections solar mass (CME) through the device data Tester Sky coronagraph MICA (Mirror coronograph in Argentina), a solar telescope and ground-based coronagraph LASCO-C1 aboard SOHO. In this research has proposed a correlation between the CME as an indicator of sky background through Sky Tester measurements observing the brightness of the sky around the solar disk called halo. We also found evidence of the correlation between the halo CME and geomagnetic disturbances through geomagnetic index "K", which indicates the type of storms that cause CMEs on the Earth's magnetosphere.
