PROBA2 witnessed on June 21 2020 a solar eclipse. The moon slided 5 times into the view of the SWAP-camera. 2 out of 5, the moon blocked partially PROBA2's solar view.
The moon could perform its show up to 5 times, because of the privileged position of PROBA2 in space while orbiting Earth.
The black disk is the moon blocking the solar view of the SWAP camera onboard of PROBA2. SWAP sees the Extreme UltraViolet (EUV) light emitted by the solar plasma. The moon appears black because it does not emit EUV.
