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 https://iopscience.iop.org/article/10.3847/2041-8213/ae71c8 - summarized in Japanese in https://www.tcu.ac.jp/en/news/all/20260609-71681/ 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.

Another view of the #ZodiacalLight behind the #Moon, from a camera on the solar cells. And the daily #ArtemisII press conferences resume now, the first one post-flyby coming up at the bottom of the hour: https://www.youtube.com/watch?v=5YWATA3d5dU

The #ArtemisII picture I had been waiting for - the dark Moon with a bit of #earthshine on the left in front of the #zodiacalLight going all around: https://images.nasa.gov/details/art002e009301 (this is essentially the Apollo 11 image from 1969 - https://www.facebook.com/dan.fischer.393/posts/pfbid02mf6UK3L2j5SgPiQsJk9JVYmo6XvZwDDZ23BYpXwJPDszaSpUYzuinkMyHzh9RF8Rl - again but with the Sun more centered ... and with half a century of photo tech inbetween).

Exactly 24 hours from now - at 0:35 UTC on 7 April - the total eclipse for the #ArtemisII crew will begin ... will they see / be able to photograph the fading detached dust tail of #Kreutz comet MAPS imaged here by #ZodiacalLight / potential dust hovering over the lunar limb might record it as well.

And here the crappy external camera with the low data rate actually delivered: the #ZodiacalLight pyramid at the beginning of the #SolarEclipse for #ArtemisII - it stayed visible in the live feed for 10 minutes! Contrary to the NASA commentary this was not the first time such an observation had been made by humans in the vicinity of the Moon - the Apollo 11 crew made it on 19 July 1969: https://www.facebook.com/dan.fischer.393/posts/pfbid02mf6UK3L2j5SgPiQsJk9JVYmo6XvZwDDZ23BYpXwJPDszaSpUYzuinkMyHzh9RF8Rl -> https://skyweek.wordpress.com/2024/07/25/allgemeines-live-blog-ab-dem-25-juli-2024/#Jul26
