This Solar Phenomenon Only Happens Twice A Year In Certain Parts of the World

This cool video from Physics Girl shows what happens during the subsolar point or Lahaina noon as they call in in Hawaii.

There are apparently no shadows in these images. But they were taken during the brightest part of the day.

There are only certain parts of the year and certain times of day when you can experience the subsolar point or Lahaina noon. There appears to be no shadow because the sun is directly overhead. This phenomenon happens twice a year for latitudes between the tropic of cancer and the tropic of capricorn at solar noon, when the sun is highest in the sky. But you have to be in the right place at the right time with no clouds! The photos and clips in this video were taken by my mom, Cathy, and friend Noel Liddell in Wailua, Po’ipu and Lawai, HI on July 11th (one day before exact Lahaina noon) and July 12th.
