Tiivistelmä

QSO B0218+357 is a gravitationally lensed blazar located at a
cosmological redshift of 0.944. In July 2014 a GeV flare was observed by
Fermi-LAT, triggering follow-up observations with the MAGIC telescopes
at energies above 100 GeV. The MAGIC observations at the expected time
of arrival of the trailing component resulted in the first detection of
QSO B0218+ 357 in Very-High-Energy (VHE, >100 GeV) gamma rays. We
report here the observed multiwavelength emission during the 2014 flare.
