Jakarta, CNN Indonesia —
National Institute of Aeronautics and Space (EIGHT) say the solar phenomenon “pethak” or Sun appears to have turned white and has the potential to occur in all parts of Indonesia.
The solar phenomenon is when the sun turns white during the day from sunrise to sunset.
“Every region throughout Indonesia has the potential to experience solar ‘pethak’,” said researcher at the Center for Science and Space Lapan Andi Pangerang quoting Between, Sunday (1/1).
According to him, when it comes to seasons, solar pehak generally only occurs in the rainy season, when water evaporation tends to be high, so cloud fog is easier to form.
“Surya pethak can only occur if the air quality at the observation location is not good, and from a meteorological point of view, the location is covered with cloud fog, so the scattering is not as strong as when the sky is clear and clear,” he said.
The cause of the white sun
The cause of the emergence of solar pehak due to volcanic eruptions and changes in sea water circulation which can affect evaporation and cloud formation.
Literally, he said, Surya “pethak” means the sun looks white. Surya “pethak” can be interpreted as the nature of sunya ruri or the day is dim like night. The day referred to here is calculated from sunrise to sunset.
According to him, the sun’s rays, which are usually reddish at sunrise and sunset, will turn white, while when the sun rises, the sun’s rays are not so hot because they are blocked by a kind of cloud.
The event can last for seven to forty days at most.
The effect of solar pehak can make the temperature of the Earth’s surface colder, so that plants cannot grow optimally and humans will easily shiver.
