【 摘 要 】

The work consists in finding and analyse solar events, such as the solar flares and coronal mass ejections and study the variation in the data counting, which can be observed by the high - rise light Cherenkov in water "HAWC" observatory, consist of 300 tanks of ultrapure water, where each of them has 4 photomultiplier tubes. HAWC is dedicated to the observation of gamma and cosmic rays with energies of TeV and has an opening that covers more of 15 % of the sky. With its wide field of view, the observatory is exposed two -thirds of the sky during each 24 hours cycle. The detector has to main data acquisition systems: the particular event and the total sum or Scalers, in this work is will make use of the counting system called TDC Scaler, which records the count rate of the number of particles which impacted on the detector in a time range.
