The two of (50000) : arxiv.org/abs/2304.09237 - besides secondary events related to already reported rings Q1R, new secondary events detected during a August 2022 in three different data sets are consistent with another ring around Quaoar with a radius of 2520±20 km, assuming the ring is circular and co-planar with Q1R; this new ring has a typical width of 10 km and a normal optical depth of ∼0.004. Like Q1R, it also lies outside Quaoar's classical Roche limit.

Doing some additional processing of the lunar frames today. Here are the best three, aligned and stacked as a composite (first image)

And another way to visualize the event (second image): the position of is held fixed, with the limb of the moving gradually away to the east. To show the changing position of the limb, the frames were rendered with different opacities.

Moon and Mars, about an hour ago, at their point of closest approach.

It’s mind-blowing to me that the Moon is so close and the Earth so big that the difference of perspective from being in Africa would put the Moon in front of the red planet!
