This is a big day on many levels. The main headline concerns Mercury stopping its forward motion and making a retrograde station at 27 degrees of Sagittarius (4:18AM PST). [Mercury will remain in reverse until December 19, when it will once again makes a direct station at 11 degrees of Sagittarius.] It's now time to begin a three-week review and reevaluation of mercurial matters -- books and papers, receipts and files, communications, business activity, classes and learning, information processing, literary and educational pursuits, travel and vacation plans. Remember that this Mercury station is directly in line with the galactic heart center. Some extraordinary visions can come your way and drastically alter your life and future. Stay alert. Another reason to remain vigilant is Mars squaring Neptune (7:27AM PST). Steer clear of confusion, nebulousness and illusions. Your emotions can be very hazy and interpersonal problems will be hard to solve. Note that the Moon in Cancer begins a void cycle during a conjunction with Saturn (8:29PM PST). Ward off fears and doubts at this time. By 2:51AM PST tomorrow, the lunar orb will enter fiery Leo.
