| Abstract: | Observations of the blazar H 1426+428 were carried with on the GT-48 Cerenkov telescope of the Crimean Astrophysical Observatory from April 15 to April 25, 2004. Analysis of the observational data shows an excess of very-high-energy photons (≥1 TeV) in the direction of the source, with a statistical confidence of 5.8 σ. A flash lasting no more than seven days was detected. |
