Resumen:

The High Altitude Water Cherenkov (HAWC) observatory is being constructed at the volcano Sierra Negra (4100 m a.s.l.) in Mexico. HAWC?s primary purpose is the study of both galactic and extra-galactic sources of high energy gamma rays. The HAWC instrument will consist of 300 large water Cherenkov detectors whose counting rate will be sensitive to cosmic rays with energies above the geomagnetic cutoff of the site (~ 8 GV). In particular, HAWC will detect solar energetic particles known as Ground Level Enhancements (GLEs), and the effect of Coronal Mass Ejections on the galactic cosmic rays, known as Forbush Decreases (FDs). The Milagro experiment, the HAWC predecessor, successfully observed GLEs and the HAWC engineering array?VAMOS? already observed a FD. HAWC will be sensitive to ? rays and neutrons produced during large solar flares. In this paper, we present the instrument and discuss its capability to observe solar energetic events. i. e., flares and CMEs. © 2013 Sociedade Brasileira de Fisica. All Rights Reserved.
