Thank you for posting that link Wei. So it seems they don't really disappear, they just get tilted and so will look like a line around Saturn instead of a belt. Does that mean, for a time, Saturn will be "unbounded"? It's very interesting that he will be conjunct Neptune...the illusion that the rings are dissolved...does that mean his full significations will be unleashed? In his Fall in Aries I really hope not ... security forces running roughshod over everyone utilizing the lie that it is for the sake of keeping everyone safe or maybe, fingers crossed, practical, creative dreams unleashed.

Wei, I think perhaps you have gotten the chart mixed up with another, or I am missing what the chart you posted is for. But the date for 2025 ring plane crossing is March 23rd. I don't have a specific time for it -I couldn't find one or any information for the duration of the event.

PS - Saturn is combust in the 2025 ring plane crossing, so it won't be visible to us but obscured by the Sun's rays. It was the same in 2009, too. It's in an article on the NASA website but all the science articles I read about the upcoming event didn't mention it. But if you cast a chart for the 2025 event, you can see it clearly.
Cheers,

Here are the charts, both tropical and sidereal, for the ring plane crossing. I found a specific time on in-the-sky.org, (March 23 2025, 16:04 UTC), and set the location for Washington, D.C.

Even though we can't see it because of the Sun's proximity to Saturn, I wonder about the mundane effect - as it's similar to the one on September 4 2009, and in contradistinction to the three events in 1995 and 1996, which were visible. It's something about the relationship between the government, symbolized by the Sun, and democracy, symbolized by Saturn?
It's an interesting and very charged time, in general, around that the 2025 ring plane crossing, as other significant phenomena are also occurring. I thought they would be worth noting in a separate post.

I heard the disappearance of Saturn's rings, and my initial thought was about the dissolving influence of Neptune.

Saturn represents the old order, while Neptune symbolizes dissolution.

Without Saturn's rings, there are no boundaries, isolation, and protection.

Aries, being the zodiac sign of new beginnings, came to mind.

I have a sense that certain existing things will vanish. What are those things, countries, or regions associated with Aries?

Charles Harvey mentioned the Saturn-Neptune cycle, which has significant connections with the British royal family in recent centuries.

The Saturn-Neptune cycle is also related to communism.

Xi Jinping has the Saturn-Neptune conjunction in Libra aligns with the Sun, Mercury, Neptune, and the South Node in the national chart of People's Republic Of China.
