DESCRIPTION:Speakers: TAM\, Pak Hin (Landessternwarte\, ZAH\, University o
 f Heidelberg\, Germany)\nGamma-ray bursts (GRBs) are among the potential v
 ery-high-energy (VHE) gamma-ray\nsources. VHE emission from GRBs is predic
 ted by most GRB models. Despite its\ngenerally fast-fading nature in many 
 wavebands\, the time evolution of any VHE\nradiation is still not clear. T
 he highest energy radiation from GRBs ever detected\nfirmly by any instrum
 ent was a 18 GeV photon coming from GRB 940217 detected with\nEGRET about 
 1.5 hour after the onset of the GRB. There is also a tentative detection\n
 using MILAGRITO of TeV excess events from GRB 970417a. In order to probe t
 he largely\nunexplored VHE spectra of GRBs\, a GRB observing program has b
 een set up by the\nH.E.S.S. collaboration. With the high sensitivity of th
 e H.E.S.S. array\, VHE flux\nlevels predicted by GRB models are well withi
 n reach. Extra-galactic background light\nabsorption is taken into account
  in cases where redshifts are known. We will present\nthe H.E.S.S. observa
 tions of and results from some of the reported GRB positions\nduring the p
 ast few years.\n\nhttps://indico.nucleares.unam.mx/event/4/session/39/cont
