The two #rings of (50000) #Quaoar: https://arxiv.org/abs/2304.09237 - besides secondary events related to already reported rings Q1R, new secondary events detected during a August 2022 #occultation 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.
Dans le ciel cette semaine :
- 10/04 #Occultation cette nuit de Sigma Scorpii (Al Niyat, mag.+2,9) par la Lune. L'occultation commence à 2h39 TU pour finir à 3h30.
- 11/04 #Mercure en élongation au crépuscule. Meilleure période pour l'observer.
- 13/04 Dernier quartier de #Lune à 09:11
- 16/04 La Lune rend visite à #Saturne, de nouveau visible dans les lueurs de l'aube.

An #occultation of #Mars by the #Moon in a recorded #webcast from #GriffithObservatory a few days ago: https://www.youtube.com/watch?v=kYNiL-DI84I - ingress at 0:36, egress at 1:29.

Doing some additional processing of the lunar #occultation 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 #Mars is held fixed, with the limb of the #Moon moving gradually away to the east. To show the changing position of the limb, the frames were rendered with different opacities.
The #Moon close to #Mars:

On https://www.youtube.com/watch?v=kYNiL-DI84I the #occultation of #Mars by the #Moon is currently streaming: ingress was captured well ('rewind' a bit), now waiting for egress.
Atención México 🇲🇽 y sur de Estados Unidos 🇺🇸
Esta noche ocultación de Marte en la Luna.

Southern North America, all of Central America, and the northernmost reaches of South America will see an #occultation of #Mars by the #Moon tonight around 0500 UTC on the 31st.
Details with times of ingress/egress for a number of sites are available from IOTA on http://www.lunar-occultations.com/iota/planets/0131mars.htm.

I am going to hazard a guess that ocultation has nothing to do with the occult.

I don’t like to compete in any way with James Webb Space Telescope (irony off); just wanted to share a photo that illustrates with how simple means it is possible to see significantly more in the sky than with the naked eye. This photo was taken some 20 years ago during a #lunar #occultation of #Saturn (on 03.11.2001). 1/3
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!

A reminder to everyone in #Ireland interested in #astronomy that tonight there will be an #occultation of the entire sky by cloud.
I hope this clarifies the situation.
