What time is the annular solar eclipse on Feb. 17?
On Feb. 17, 2026 (ET), an annular solar eclipse will turn the sun into a dramatic "ring of fire" for observers along a narrow path in Antarctica, while much broader regions will see a partial eclipse. Here’s what skywatchers need to know about timing, visibility and safety.
When and where the eclipse will be visible
The eclipse on Feb. 17, 2026 (ET) is an annular event, meaning the moon will pass between Earth and the sun but will appear slightly too small to cover the sun’s disk completely. At maximum, that smaller-appearing moon will leave a bright outer ring of sunlight visible — the so-called "ring of fire" — for up to 2 minutes and 20 seconds at the point of greatest annularity.
Annularity follows a narrow corridor about 2, 661 miles long and roughly 383 miles wide (4, 282 by 616 kilometers). Only a very small region of Antarctica falls within that corridor, where the moon will cover about 96% of the sun's disk. Outside the path of annularity, much larger areas of Antarctica and portions of southern Africa and the southernmost reaches of South America will experience a partial solar eclipse, with the sun appearing progressively more covered depending on location.
Because the path of full annularity lies in Antarctic latitudes, the best on-the-ground viewing opportunities for the full "ring of fire" will be limited to expedition-style trips or scientific operations based on the continent. Most casual observers in populated regions will see only a partial event.
How to observe safely and what to expect
Never look directly at the sun without proper protection. Whether you are observing a partial or an annular solar eclipse, the same safety rules apply: use certified solar eclipse glasses to view the sun, and ensure cameras, binoculars and telescopes are fitted with proper solar filters placed over the front of the optics at all times. Regular sunglasses are not safe for solar viewing.
During annularity the bright ring remains intense; even though the sun's disk is mostly obscured, the exposed rim is capable of causing eye damage. If you are photographing the eclipse, attach solar filters to lenses and follow manufacturer guidance. Observers using public viewing events should follow the instructions of on-site organizers and safety officers.
Expect the sky to dim noticeably during the peak phase of the eclipse and for ambient light to take on an odd, twilight-like quality in regions experiencing deep partial coverage. Temperatures can also dip briefly as sunlight is reduced.
What comes next for skywatchers
Skywatchers who miss the Feb. 17 annular eclipse have a pair of notable events to look forward to later in 2026. A total solar eclipse on Aug. 12, 2026 (ET) will cross parts of Greenland, Iceland and northern Spain, with a wide partial eclipse visible across broader areas of Europe and Africa. Before that, a total lunar eclipse on March 3, 2026 (ET) will deliver a deep, blood-red moon visible from North America, Australia, New Zealand, East Asia and the Pacific.
For anyone planning to travel to see eclipses, check detailed local timing and viewing maps well in advance, prepare proper eye protection, and be ready for remote or challenging conditions when chasing events that occur in high-latitude or polar regions.
