antisolar point
Sun's exact opposite
The antisolar point is the spot in the sky directly opposite the sun from an observer's perspective—always 180 degrees away.
It lies at the center of phenomena like the glory (colored rings around an airplane's shadow on clouds) and is where rainbows form their arc.
At night, the antisolar point is above the horizon; by day, it's below your feet.
