ZERO SHADOW DAY
What’s in news?
The day was observed in various parts of the state Maharashtra from May 16. In Aurangabad, the shadow was completely vanished during the noon on May 18.
- The lack of shadow happens twice a year, for places between +23.5- and -23.5-degrees latitude.
- The Sun is almost never exactly overhead at noon, but usually transits a bit lower in altitude, a bit to the north or a bit to the south.
- Earth’s rotation axis is inclined at 23.5 degrees to the plane of its revolution around the Sun, which is why we have seasons.
- For people living between +23.5- and -23.5-degrees latitude, the Sun’s declination will be equal to their latitude twice – once during Uttarayan and once during Dakshinayan. On these two days, the Sun will be exactly overhead at noon and will not cast a shadow of an object on the ground.
- The Zero Shadow Day will clearly be different for different places on earth.
- Even if Zero Shadow Day happens again in July when the Sun is on its southward journey, it often cannot be observed properly due to rainy season.
