On June 12th at noon, the vertical ray of the sun will strike the Tropic of Cancer, which is located at approximately 23.5 degrees North latitude.

This is because June 21st marks the summer solstice in the Northern Hemisphere, and the Sun reaches its highest declination, meaning it is directly overhead at the Tropic of Cancer.

Therefore, on June 12th, which is close to the summer solstice, the sun will be very close to being directly overhead at the Tropic of Cancer at noon.
