The Sun is about to leave Leo, but not quietly; before it enters the Mercury-ruled sign Virgo tomorrow at 7:21 a.m. EDT, it opposes Neptune in the last degree of Aquarius.
There is much debate among astrologers as to the meaning of cusp degrees; I personally feel that if a planet falls in the last degree of a sign, it certainly exhibits all the traits of that sign, period. What can and does vary is capacity of the individual who has that cuspal degree, either in the natal chart or by progression, to recognize that a cosmic page is about to be turned and "the times they are a-changin'." Some highly attuned individuals may feel unstable or insecure despite their power or accomplishments, while others feel optimistic and excited about the big change about to happen. Some are more apt to reflect upon the total sum experience of whatever zodiacal sign of the planet that falls on the cusp, while others home in on the need to clear the decks for the next sign. The fixed signs (Taurus, Leo, Scorpio, and Aquarius) are the most likely to hang on by their fingernails, while the mutable signs (Gemini, Virgo, Sagittarius, Pisces) are the most likely to let go.
The Sun opposing Neptune is far from an easy aspect, nor is it easily pinned down, because Neptune itself is a slippery fish. In some ways we will feel a similar vibe to yesterday's Venus-Neptune opposition; however, while the Venus-Neptune opposition (again, in the last degrees of Leo and Aquarius, respectively) may have played out as disappointment, sadness, or deception (either to yourself or your romantic partner), the Sun-Neptune opposition will have more to do with how you perceive yourself. It will be distorted, as if you are gazing into a fun-house mirror, without the fun. You may find yourself in the throes of an identity crisis. Your faults may look like virtues, and vice versa.
Neptune is the consummate dreamer and idealist of the solar system, and the Sun forming an opposition to it encourages us to engage in fantasy and escapism. This may not be so bad in the short term for down-to-earth types, but for those of us who already have our heads in the clouds, or imbibe in alcohol or hard drugs, it can be very dangerous. You are far more likely to trust the wrong people under this aspect, and yet it is equally hard to trust yourself.
This can feel like a no-win situation, but you may reap the unexpected benefit of waking up from wishful thinking, or living, that left you drifting aimlessly toward a waterfall.
