On June 8, 2021, a strange spiral appeared in the skies over the south Pacific islands of New Caledonia and Vanuatu.
The greenish spiral, which people noted looked straight out of Marvel's Doctor Strange movie, turned out to be fuel released by China's Long March rocket.
From L'Association Calédonienne d'Astronomie Facebook page:
Jonathan McDowell, an American astronomer who lists all maneuvers and orbital launches on the planet, has confirmed it was the second floor of a Chinese Long March 2 C rocket, which took off June 18 at 06 h25 UTC from Xichang launch center, with 4 satellites on board.
