What time is the total solar eclipse on Dec. 4?
Update for Dec. 4, 2021: The total solar eclipse of Dec. 4 has ended over Antarctica. You can see a video above and see photos and our full wrap story here.
If you’re ready to catch the only total solar eclipse of 2021 on Saturday (Dec. 4), you likely are either a research scientist, a well-heeled tourist or a penguin.
That’s because the prime location for the total phase is in Antarctica, although there may be a livestream available. The partial phase starts at 2 a.m. EST (0700 GMT), the nearly two-minute totality phase — when the moon completely blocks out the sun — starts at 2:33 a.m. EST (0733 GMT), and the whole eclipse ends at 3:06 a.m. (0806 GMT), according to NASA.
If you can’t make it there in person, weather permitting, NASA plans to broadcast the total solar eclipse from Union Glacier, Antarctica on YouTube and nasa.gov/live. The stream starts at 1:30 a.m. EST (0630 GMT), totality begins at 2:44 a.m. EST (0744 GMT) and the stream ends at 3:37 a.m. EST (0837 GMT).

Some of the luckiest humans to see the total eclipse include the estimated summertime population of 40 at the National Science Foundation’s Antarctic Palmer Station, or tourists who caught scheduled eclipse flights at a price of thousands of dollars a seat.
The partial phase of the eclipse will be visible from the southernmost regions within Australia, New Zealand, Argentina and South Africa, according to an interactive map from Time and Date.

If you happen to be within reach of the eclipse, either partial or total, make sure to use precautions to safely observe the sun. You will need special protective eyewear or certified eclipse glasses. Eyeglasses will not protect you, even with UV protection. The safest way to observe an eclipse is indirectly, using a pinhole camera that you can make easily at home.
If you can’t catch this eclipse in person or online, your next opportunity is April 20, 2023. That total eclipse will pass over southern and eastern Asia, according to NASA’s eclipse site.
