The HAWC GRB programme

HAWC is a very-high-energy gamma-ray observatory operating in central Mexico at an altitude of 4, 100 m above sea level. It has an instantaneous field of view of 2 sr and surveys 2/3 of the sky every day. The duty cycle (up time fraction) of over 95% and the lack of observational delays make HAWC an ideal detector for studying transient sources like gamma-ray bursts (GRBs) at energies as small as 50 GeV. This contribution summarises the current efforts of the HAWC GRB programme: a fast follow-up of GRBs reported by satellites and a real-time, untriggered search of the entire overhead sky are running at the HAWC site. New results on recent Swift and Fermi GRBs will be shown.
