Utilizing the LHAASO-WCDA real-time alert system, here we report the detection of a TeV gamma-ray flare from Markarian 501. LHAASO-WCDA The observed gamma ray flux enhancement from the blazar starting at MJD 60446.77. Up to 60447.77 the accumulated significance reaches 8 s.d., with a flux of ~0.9 Crab Unit above 1 TeV.
LHAASO is a multi-purpose Extensive Air Shower (EAS) array designed to detect gamma- rays and cosmic rays air showers in a wide energy range, from sub-TeV to beyond 1 PeV.
