Light curve of η Carinae from 15 November to 5 December in 2019. In black, dedicated analysis between 100 MeV and 500 GeV with Fermi-LAT (2-day bins, requiring at least 2σ for detection). The corresponding average flux is represented with a grey line. The γ-ray flux enhancement reported by AGILE is shown in green (Piano et al. 2019), which overlaps with the X-ray light curve peak on 28 November 2019, indicated by a violet dashed-line (Corcoran et al. 2019).
