MAGIC made an observation in the period of the main prompt emission!! But we knew later z = 6.3
Summary • MAGIC Sources • We have seen ~15 sources including several new sources • Micro-Quasars are playing an important role as a source of galactic cosmic rays • New 100GeV HBLs show steep spectra • The attenuation by e+- creation • The nature of SSC mechanism • GRB observations • 2 among 9 observations were done in prompt phase • Eventually MAGIC may see VHE gammas from GRBs • Second telescope MAGIC-II is under the construction in La Palma • Next year we will start stereo observation 2 times better sensitivity number of sources may increase ~50 • HESS and MAGIC people are planning CTA after HESS and MAGIC experiment • 10 times better sensitivity than HESS and MAGIC • 1000 VHE sources in norhtern and southern hemisphere
