Description

BL Lacertae is a well-known high-energy BL Lac object that has exhibited several epochs of very high energy (VHE) gamma-ray flaring events. On October 5, 2024 (MJD 60588), BL Lacertae underwent prominent flaring activity, which was detected by instruments covering a wide energy range from optical to TeV gamma rays. In this work, we aim to study the spectrum and variability of BL Lacertae based on the quasi-simultaneous multi-wavelenth data.
