The MAGIC telescopes observed an increased flux at very-high-energy (VHE; >100 GeV) gamma rays from the radio galaxy M87 (RA=12 30 47.2, Dec=+12 23 51, J2000.0, z=0.0044). The preliminary analysis of the MAGIC data taken on 2021/03/23 (MJD 59296) indicates a flux of about 7% of the flux from the Crab nebula above 350 GeV, which implies an increase by a factor of about 6 with respect to the typical VHE flux from this source. MAGIC observations on M87 will continue and multiwavelength observations are encouraged. The MAGIC contact persons for these observations are O. Blanch (blanch@ifae.es), D. Mazin (mazin@icrr.u-tokyo.ac.jp) and A. Hahn (ahahn@mpp.mpg.de).
MAGIC is a system of two 17m-diameter Imaging Atmospheric Cherenkov Telescopes located at the Canary island of La Palma, Spain, and designed to perform gamma-ray astronomy in the energy range from 50 GeV to greater than 50 TeV.
