The phenomenon of bright rays shining out of the temple’s 15 doorways can be witnessed from 5.55pm to 6.30pm on Wednesday, Thursday and Friday.
The local office of the Fine Arts Department said the temple complex will be closed half an hour later at 6.30pm on the three days.
It said visitors should be able to witness the natural phenomenon provided it doesn’t rain and there are no clouds blocking the sun.
Prasat Hin Phanom Rung in Buri Ram’s Chalerm Phrakiat district is a majestic Khmer temple believed to have been built between the 10th and 13th centuries to worship the Hindu god, Shiva.
A similar phenomenon was witnessed at the temple last month, when the sun aligned perfectly to shine its rays through the 15 doorways while rising at 5.45am on September 9, 10 and 11. However, low clouds dimmed the spectacle.
