In simple words
A transit is where a planet is in the sky now, compared with your birth chart. Here, today's Sun makes a opposition (180°) to the spot where your rising sign was when you were born.
It is a time of pressure that pushes you to grow, and it lasts two or three days. Your Today page tells you when it is happening for you.
Love
Close relationships come into focus. Give them care.
A good time to clarify commitments.
Listen deeply to a partner or close friend.
Work
Collaboration and contracts matter now.
Let others lead where they are strong.
Agreements made now can last.
Mood
Outward-focused. Keep some time for yourself.
Others' energy affects you strongly.
Balance giving with receiving.
About the opposition
An opposition places two planets across the sky from each other. Each one pulls toward its own side of life. Oppositions are often felt through relationships, as if another person plays one side. The work is balance: holding both needs instead of swinging between them.
