What is the constellation on August 9th?

Leo: Enthusiastic and cheerful, bold in doing things, domineering, regal, fond of playing big cards, unreasonable, arrogant, face-saving, super-controlling, dare to love and hate, capable of being a leader in a group, but extremely aggressive in doing things and thinking, so you can't accept or even indulge yourself as long as you encounter a little setback.
