Green Flags are supportive relational indicators that show where synastry creates ease, resonance, and constructive flow. They highlight natural compatibility, emotional coherence, and mutual uplift across all relationship types.
Why the Sun Matters
The Sun represents identity, vitality, purpose, and the core of who we are. In synastry, it shows how two people illuminate one another — where confidence grows, where recognition flows naturally, and where each person feels seen at their center. When someone’s Sun touches a part of your chart, that area tends to feel warm, affirming, and aligned with your sense of self.
The Sun’s Timing
The Sun spends about one month in each zodiac sign, moving with steady predictability through the year. This makes Sun overlays common and easy to feel — they often show up as immediate recognition, natural rapport, or a sense of “I understand who you are.” Sun synastry highlights where two people naturally affirm and energize one another’s core identity.
