The PMD said the eclipse will be visible in parts of Africa and South America. It added that a partial solar eclipse will also be seen over the Atlantic Ocean, the Pacific Ocean and the Indian Ocean.
The department said the "Ring of Fire" will be visible only in Antarctica.
In an earlier update, the PMD described the phenomenon as an annular solar eclipse, during which the moon covers most of the sun while leaving a bright ring of sunlight visible around its edges.
Space.com reported that the "Ring of Fire" will be observable from a remote region of Antarctica, where up to 961f the sun will be obscured for just over two minutes.
The report said a partial solar eclipse will be visible across parts of Antarctica, southern Africa and the southern tip of South America, while regions over the Atlantic, Pacific, and Indian Oceans will also witness a partial eclipse.
The PMD said Pakistan will have two solar and two lunar eclipses this year, though it noted that today's event will remain inaccessible to observers in the country.
Astronomers and eclipse enthusiasts worldwide are encouraged to follow the phenomenon via live broadcasts or online streaming, as the full annularity will be seen by very few people on Earth in person.
