The High-Altitude Water Cherenkov (HAWC) Observatory is a ground-based TeVgamma-ray observatory in the state of Puebla, Mexico at an altitude of 4100 mabove sea level. Its $\sim$22,000 m$^2$ instrumented area, wide field of view(2 sr), and $>$95% uptime make it an ideal instrument for discovering gamma-rayburst (GRB) emission at $>$100 GeV. Such a discovery would provide keyinformation about the origins of prompt GRB emission as well as constraints onEBL models and the violation of Lorentz invariance. We present here the resultsof our current GRB search methods, which include an all-sky search as well asfast follow-ups of GRBs reported by satellites, after one and a half years ofdata with the full HAWC detector.

Results from the first one and a half years of the HAWC GRB program
