This can be a harsh transit, but the changes that you will experience you probably already regard intuitively as necessary. I lost my dad when Saturn and Pluto conjoined right on my Sun in 4th. With your Sun in 11th you’ll probably see some friendships end, and the new ones start. The new ones should be more empowering.
T pluto in 11th suggests power struggles with friends, and quite possibly some end.
“There may be attempts by others to sway your opinions or change your beliefs for political ends. You may come into contact with radical ideas in religion or philosophy. This combination represents religious extremism, terrorism, and vigilantism. Often there is the need to deal with corruption in connection with ethics and morality. You may be either a victim or perpetrator of the abuse of power or authority. There may be a temptation to overstep your jurisdiction or authority on some issue during this period. Remember that two wrongs don’t make a right.” http://www.astrology-x-files.com/transits/pluto-op-jupiter.html
A lot really depends on how jupiter is aspected and for this we need to see a chart please?
Maybe this description of this transit by Jamie from darkstarasrtrology.com can give you some more clues:
Pluto transits herald major life changing experiences and this is especially so with transiting Pluto conjunct Sun. The Sun is the life force, the power and the whole identity and there is an eighteen month period of deep and lasting change in the life direction. Pluto has a reputation of stripping away things to the bare bone in order to facilitate soul evolution, however this does not have to be the case with this conjunction. There may be events which result in loss or separation, but only if those things are standing in the way of being true to yourself.
By studying a few examples of this transit in celebrities, we can see that transiting Pluto conjunct Sun is very empowering, and that this phase of life, although intense and full of change, leads to great personal and professional advancement that is more in tune with the souls desire.
Leonardo DiCaprio experienced Pluto conjunct Sun from late 1990 through to the end of 1991. He was just sixteen years old then and already had some experience in TV commercials. But it was Pluto that brought the big breakthrough, firstly in a few appearances in TV shows in 1990 just as Pluto was approaching his Sun. Then in 1991, with Pluto right on his Sun, Leonardo got his break on the big screen with Critters 3, and then also that year he landed a starring role on the high rating TV show Growing Pains.
Prince Charles had Pluto conjunct Sun from late 1992 through to the end of 1993. This marked a major turning point in the Prince’s life. He had not been living true to his soul’s desire, and in December 1992 it was formally announced in parliament that he had separated from his wife, Princes Diana. In 1993, Pluto revealed his secrets, with the media release of private phone calls between the Prince and his true love, Camilla Parker-Bowles.
Jodie Foster had Pluto conjunct Sun all of 1994. She starred in two very successful films that year, Maverick and Nell, the later winning her critical acclaim and three gongs for the trophy cabinet. Jodie also produced Nell.
Brad Pitt saw Pluto on his Sun all of 2006, a very intense and life changing year for him. Professionally, he starred in the critically acclaimed film Babel, which he stated was “one of the best decisions of my film career”. In his personal life, January 2006 saw Brad legally adopt Anglina’s adopted two kids, and they surnames were changed to “Jolie-Pitt”. January was also the first time their relationships was publicly confirmed. On 27 May 2006, just 14 days after the second conjunction of Pluto to his Sun, Angelina gave birth to their daughter Shiloh Nouvel. They made $10 million from the sale of images of their baby, and gave it all away to charity.
