KUALA LUMPUR: The residents here will experience “a day without shadow”, or a phenomenon called equinox, on March 29 and Sept 15.
National Space Agency (Angkasa) assistant information officer Asmidar Zainol said the phenomenon would occur at 1.10pm when the sun was overhead at noon.
“During this phenomenon we will not be able to see our own shadow when standing in the sun in the open.
“However, the phenomenon is not peculiar because it takes place twice every year,” she said in a statement.
The equinox occurs due to the passage of the Earth around the sun with the plane of the Earth tilting at an angle of 23.5 degrees.
Asmidar said areas that would experience this phenomenon were those in the latitude of 23.5 degrees north and 23.5 degrees south.
During the equinox, the sun will be right overhead at 0 degrees latitude and occurs precisely at the Equator.
Besides Kuala Lumpur, people in Langkawi, Kedah, can experience the equinox on April 6 at 1.24pm and on Sept 6 at 1.20pm while those in Pontianak, Indonesia, can experience it on Sept 23.
