Description
MAGIC and FACT investigate the very-high-energy (E>100GeV) gamma rays emitted by blazars, whose relativistic jets points towards the observer. Past observations have revealed that the blazar 1ES2344+51.4 can show strong flux variability and the spectral energy distribution shifts towards unusual high energies during flares. We report a flaring episode of 1ES2344+51.4 during August 2016, where the VHE flux measured by MAGIC and FACT is comparable to the historical maximum, while the spectrum is the hardest for this object above 100GeV. Combining multi-wavelength observations, we obtain an unprecedented characterisation of the inverse Compton peak.
