Mars entered Pisces November 15, and is in a square (clash) with Jupiter through the full moon, November 23.
Pisces rules the 12th house of endings, things secret and hidden, Dr.'s, hospitals, places of seclusion. Pisces planetary rulers are Jupiter and Neptune. Neptune can involve great creativity and imagination or it can represent illusion, delusion and confusion, as well as drugs, alcohol, and religion or spirituality. Pisces is one of the most compassionate of signs and its element is Water.
Mars is square Jupiter, the planet of expansion and gain and many things and situations can become blown out of proportion.
With Mars in Pisces and Jupiter in Sagittarius, we could see confused or incorrect information and situations getting blown up and of control, like the out of control wildfires in California. Sagittarius is the most expansive of signs and tends to take off in its own direction. With Mercury retrograde (in Sagittarius) the direction could be confused.
Expect to see major events in the world over the next week, and is often the case these days, especially in politics.
