The IceCube Neutrino Telescope at the South Pole, completed in December of 2010, consists of 5160 Digital Optical Modules (DOMs) mounted on 80 vertical 1-km long strings arranged in a hexagonal pattern. Each string contains 60 DOMs located at a depth of 1450–2450 meters under the ice. The closely spaced inner arrays in the deepest ice, called DeepCore, enables the IceCube Neutrino Observatory to detect neutrinos at energies as low as 10 GeV. A special SN trigger based on a ≥ 6σ excess on top of the dark count-rate background in the DOMs is used to indicate a possible SN explosion. A close study of solar activities due to the onset of the solar cycle 24, revealed correlations between the IceCube Supernova trigger events and increased solar activities. In this thesis, we discuss these correlations and present the results and overall contribution of possible backgrounds due to the seasonal variation of the atmospheric muons. We conclude that these triggers are the results of high energy neutrino production in the sun. We expect the rate to increase with the maximum of the solar activities in mid 2013 and subsequently drop afterwards.
