Abstract: We report multiwavelength observations of the gravitationally lensed blazar QSO B0218+357 in 2016-2020. Optical, X-ray, and GeV flares were detected. The contemporaneous MAGIC observations do not show significant very high energy (VHE; greater than or similar to 100 GeV) gamma-ray emission. The lack of enhancement in radio emission measured by The Owens Valley Radio Observatory indicates the multizone nature of the emission from this object. We constrain the VHE duty cycle of the source to be<br />Monthly Notices of the Royal Astronomical Society, 510 (2)<br />ISSN:0035-8711<br />ISSN:1365-2966<br />ISSN:1365-8711
