by the sting of the trail of totality.getty
Witnessing a complete photo voltaic eclipse usually requires excessive precision—and “99% totality” doesn’t exist. The moon’s darkish central shadow—its umbra—will transfer throughout North America on April 8 at round 1,500mph, throwing the land beneath it into darkness. In its wake will likely be hundreds of thousands of shocked onlookers contemporary from seeing the solar’s wispy white corona with their bare eyes.
The umbra, nevertheless, has edges. Its projection is named the trail of totality for a purpose. Stand anyplace inside its boundaries, and also you’ll witness one thing totally extraordinary. Stand to the facet of the umbra—even 1 / 4 of a mile past its boundaries—and also you’ll merely see a partial photo voltaic eclipse, which may solely be seen by means of photo voltaic eclipse glasses or photo voltaic viewers.
The difficulty is, 1000’s of cities and cities in North America are both break up in two by, or are on the mistaken facet of, the sting of the trail of totality. It means they’ll solely see a 99.9% partial photo voltaic eclipse—and norhing of the overall photo voltaic eclipse.
Get Into The Path
The very best tactic in case you’re anyplace close to the trail’s edge—whether or not since you reside there or as a result of it’s the one place you could possibly safe lodging—is to move farther into the trail. It’s pointless to succeed in the centerline, the place the period of totality would be the longest within the area, however purpose for at the least a few minutes if totality. The oval form of the moon’s shadow signifies that about midway between the centerline and the sting will get you about three-quarters of the period.
Should you reside in, or will likely be staying in a single day in, any of those locations—or anyplace else simply outdoors of the trail—stand up severely early and plan to spend the complete day in a location a lot farther into the trail of totality.
So listed below are 15 “edge” areas that should be prevented in any respect prices in case you’re to expertise a complete photo voltaic eclipse. I’ve chosen solely the most important cities, however the identical applies to 1000’s of small cities which are on the dividing line between totality—and 0 totality. intersected by the trail of totality.

Texas: San Antonio, Austin And Denton
Solely the northwest suburbs of San Antonio are throughout the path of totality—the town heart and its well-known Alamo and River Stroll will likely be outdoors of the trail of totality and see nothing of the overall photo voltaic eclipse. In Austin, the scenario isn’t fairly as dangerous, with Downtown Austin within the path, however the southeastern suburbs of the town—together with the airport—are outdoors the trail. Denton, on the far north finish of the Dallas-Fort Price metroplex, will get a 99.95% partial photo voltaic eclipse—simply journey southeast to the southern half of Lewisville Lake for a brief totality.
Arkansas: Fort Smith
You should utilize Fort Smith, on the Arkansas-Oklahoma border, as an in a single day base and journey to Mount Ida or Russellville areas. However don’t keep there on April 8 as a result of its heart will get a 99.9% partial photo voltaic eclipse. Solely its southern suburbs get a brief totality.
Crawfordsville (proper).Dan McGlaun/Eclipse2024.org
Indiana: Frankfort, Kokomo And Crawfordsville
These on the southeast facet of Kokomo, Indiana, will glimpse totality for a couple of seconds. Everybody else will see a 99.99% partial photo voltaic eclipse. It is the identical with the far southeast nook of Frankfort, whereas Crawfordsville is simply inside the trail however has a super-short totality.
New York: Rome And The Finger Lakes
Rome will get a irritating 99.95% partial photo voltaic eclipse, and so will the southern reaches of a few of the 11 “Finger Lakes” in New York. the trail of totality.Dan McGlaun/Eclipse2024.org
99% Cities Shut To The Path To Keep away from
There are a number of actually huge cities near the trail of totality on April 8, together with St Louis, Missouri (99.1%), Fort Wayne in Indiana (99.9%), then three large cities lined-up on the southern edge—Louisville (99.2%) in Kentucky, Cincinnati (99.7%) and Columbus (99.8%) in Ohio—in addition to Ithaca in New York (99.1%).
‘Grazing Zone’
Alongside the sting of the trail of totality a “grazing zone” exists the place no-one is totally positive what will likely be seen. The problem is, surprisingly, the solar’s diameter, which seems to wax and wane sufficient for the projection of the moon’s shadow to barely fluctuate in width. The varied maps out there of the trail of totality use totally different values for the solar’s diameter, so a location that seems to be simply throughout the path of totality on some maps appears simply outdoors on others.
