Part of the light curve at 2.2 μm. Top: Flare A during the period t ∈ [86, 150] min (the first bright flare with approximately 7 mJy radiation flux). Bottom: Flare B during the period t ∈ [879, 926] min (a bright flare with two peaks). The duration of the flares is about 40–60 minutes. We divided the light curve into three states: pre-flare, dim state, and bright state. This separation is based on the flux and spectral index
