The Narit said the moon will turn a deep shade of red as it is eclipsed fully by the Earth’s shadow from 5.44pm to 6.41pm on Tuesday – 57 minutes in total.
The Narit said the eclipse event will start at 3.02pm and end at 8.56pm in Thailand and will also be visible in many other parts of the world.
To observe the eclipse, people should observe the eastern horizon where they will see the moon turn brick-red from 5.44pm, Narit said.
Thailand will have to wait another three years for the next total lunar eclipse, on September 8, 2025.
Narit has invited Loy Krathong revellers to dress in traditional Thai costume and watch the phenomenon at four national observatories:
- Sirindhorn Astronomical Park in Chiang Mai’s Mae Rim district
- Chalermphrakiart Observatory in Nakhon Ratchasima
- Chalermphrakiart Observatory in Chachoengsao
- Chalermphrakiart Observatory in Songkhla.
The four observatories will hold lunar eclipse activities from 6pm to 10pm.
