The 2nd contact of the #ArtemisII solar eclipse filmed with an out of focus (!) cellphone: #corona streamers appearing. (During most of the eclipse only the #ZodiacalLight had been visible behind the huge Moon as the paper iopscience.iop.org/article/10. - summarized in Japanese in tcu.ac.jp/en/news/all/20260609 which auto-machine-translates into English - has explained.)

This slide from the #coronagraphs symposium in Boulder from the talk by Sam van Kooten is quite enlightening: it shows two processing steps of a #PUNCH WFI composite, on the left still dominated by the F corona i.e. #ZodiacalLight i.e. interplanetary dust (just as seen in the Artemis II eclipse images) while on the right the - at such distance from the Sun muuuch fainter - K corona has been brought out which traces the Sun's magnetic field.
