On 21 December 2010, there will be a lunar eclipse at 29 degrees Gemini which is highly stressed by planets in Sagittarius and Pisces. This leaves people with planets in the late degrees of Virgo, the fourth mutable sign to contend with the brunt of of this. People with planets in the early degrees of Libra will also be impacted.
What is apparent about this Full Moon is its emphasis on Mercury (communication). We have got Gemini, Virgo and Mercury involved, along with Sagittarius and Jupiter and when you put this together there is no end to the blurting and boasting and broadcasting we are going to see going into this.
It would be mindful not to go about talking to much otherwise you may very well "break" your mouth or your mind in the process. Those who are clever enough to joke while they are preaching will be in very high tide with this.
