YOGYAKARTA The culmination of the Sun is an annual natural phenomenon that can be felt in Indonesia. Even though it occurs every year, there are still many people who do not know that the phenomenon of solar culmination is. This article will provide an explanation of the natural phenomenon of solar culmination for you.
Reporting from the website of the Meteorology, Climatology and Geophysics Agency (BMKG), culmination is a phenomenon when the position of the Sun is at the highest point of the sky. This phenomenon has another term, namely 'Special' or main culmination.
During the culmination, the position of the Sun is in the zenith totok or above the head. As a result, the image of an upright object seems lost because it is piled up with the object itself. The effect of culmination then developed in society as a phenomenon without a shadow.
In a study entitled Education on the Culmination Phenomenon and its Impact on the people of Pontianak City which was published in Buletin Al-Ribaath, it was explained that the culmination occurred because the movement of the earth's revolution when it surrounded the Sun would experience a dynamic slope.
The maximum inclination of the earth's rotation axis in the ecliptic plane is 23.5 degrees. The dynamics of the tilt of the rotation axis then causes the pseudo motion of the Sun.
The phenomenon of the qualification of the Sun in Indonesia occurs twice a year. This is because Indonesia's position is on the equator. Usually the day without a shadow itself occurs around March and September.
In 2025, the main culmination in Indonesia will take place from February 20 at Baa, East Nusa Tenggara until April 4, 2025 in Sabang, Aceh. Then the second culmination will occur on September 7, 2025 in Sabang, Aceh until October 21, 2025 at Baa, East Nusa Tenggara.
Although it is natural to happen, people need to prepare themselves for the phenomenon of solar culmination. Here are some impacts of the phenomenon without a shadow.
When the Sun is at its highest point, the shadow will disappear so that the light will appear hotter than usual. For some people the heat of the excessive light will interfere with the vision.
As is known, sunlight contains radiation and a high Ulta Violet, especially at certain hours. When the dominance occurs, the potential for radiation and UV increases is higher than usual.
On a day without a shadow, the sun's rays will appear hotter and an increase in temperature may occur. However, the potential for this temperature increase does not occur significantly because usually temperature increases can occur due to weather or climate factors.
Although it does not bring a significant harmful effect, the community needs to anticipate certain impacts caused by the culmination phenomenon. The following are anticipatory steps that can be taken.
