By midday the date, the Sun is almost directly above the head. Today, a monument or object that stands firmly on the equator will seem barely a shadow.
Although this natural phenomenon is called a day without shadows, shade trees will still have a shadow. Also before and after midday the monument will again have a shadow.
National Aeronautics and Space Research Center (LAPAN) Space Researcher, Rhorom Priyatikanto, cited Thursday, March 15, 2018, exposed the impact of the phenomenon of the day without a shadow later.
First, because the Sun passes just above the head, then the impact of the Sun will be more blistering 9 percent compared to the time of solstice. To note, the solstice is a moment when the Sun is at the northernmost and southernmost point. Solstice marks the peak of summer or winter.
The summer peak occurs around June 22, while the peak of winter occurs around December 22.
The second impact, said Rhorom, there is no change in the acceleration or gravity of the Earth or the Sun. Furthermore, the third impact of the day without a shadow that began to occur seasonal changes in the territory of Indonesia.
On March 21, 2018, the shadow of LAPAN will participate in the Shadow Nine Day Festival in Pontianak City, West Kalimantan. The festival will run until March 23, 2018. LAPAN will present mini planetarium shows, exhibits, and educational lectures.
