Partial solar eclipse marks summer solstice
People in Thailand can watch on Sunday (June 21) a "partial solar eclipse" on summer solstice, the longest day of the year.
Looking at the sun with naked eyes is dangerous.
The National Astronomical Research Institute of Thailand (NARIT) said that on June 21, there will be a "partial solar eclipse", visible in Thailand from 1pm to 4.10pm.
In Thailand, the sun rose at around 5.51am on Sunday and will disappear from the horizon at approximately 6.47pm, appearing on the sky for 12 hours and 56 minutes.
The summer solstice ccurs when one of the Earth's poles has its maximum tilt towards the Sun.
Northern Hemisphere countries count the day as the start of summer while in the southern hemisphere, daytime is the shortest and marks the beginning of winter.
