Millions of people across Indonesia and the Pacific are being treated to a total solar eclipse.
From this morning, the Moon will pass directly in front of the Sun, blocking all direct sunlight and turning day into night.
The eclipse will be total in Indonesia and the Central Pacific, while parts of Australia and east Asia will experience a partial one.
People along a 150km-wide strip running through Sumatra, Borneo and Sulawesi - the path of eclipse totality - will experience a blackout from about 7:00 to 11:00 local time.
The partial eclipse will start about an hour from now and the total eclipse will take place an hour after that.
Astronomers have reiterated advice not to look directly at the Sun with the naked eye, or through a telescope.
