Liputan6.com, Jakarta - National Aeronautics and Space Agency (LAPAN) said that Indonesia on Wednesday (21/3/2018), experiencing a rare phenomenon that is, a day without shadow. This can happen because the sun is right above the equator.
Given this natural phenomenon will occur at 12 noon, where the sun is above our heads. Objects that stand upright on equator or equatorial line can be sure will experience no shadow.
According to Head of Public Relations Division LAPAN, Jasyanto, a day without shadow occurs because the earth circulates around the Sun at a distance of 150 million kilometers with a period of about 365 days.
"The Earth's circular lines are somewhat oval, so the Earth sometimes moves faster and sometimes moves more slowly," according to a written report. Jayanto also explained that the change in the position of the sun caused a change of seasons on a number of continents.
Astronomers and scientists say that the equinox that occurred in March is a sign of the emergence of summer in the country in the northern hemisphere and winter in the south. Indonesia has also experienced wet-dry season changes due to this shadowless day.
Uniquely, this phenomenon occurs only in areas that are in the equator line only. However, this phenomenon does not only occur in the famous Pontianak passed by the equator with the latitude of 0 °.
According to LAPAN, other areas that will experience a day without shadows include Bonjol, Bontang, Riau, Parigi Moutong, Kayoa Islands, Amberi, Gebe, The area can experience a day without a shadow because it is close to the equator.
Although unique, there is also the impact that arises from this natural phenomenon. In Indonesia, the Sun will provide a more hot temperatures during the day. Then the famous ionosphere coating helps to reflect radio telecommunication waves, can be inhibited.
So there is a big possibility that radio communication interference may occur. However, it does not make the signal on our communication tool completely lost. This rare phenomenon usually occurs for two times a year on 21 March and 23 September.
