WHY ARE THE PREDICTED COORDINATES AND TIME OF THE ECLIPSE CHANGING and WHAT IS THE TRUTH?
'New' path of totality map shows more parts of Texas will get to see the solar eclipse

Despite modern technology, the sun's radius is difficult to measure. New data shows that the sun is a tad bigger than previously thought.
These new calculations have slightly shifted the solar eclipse's path of totality — just a week before the event.

Expert John Irwin has recently published a new map with updated lines for the April 8 solar eclipse, Forbes reports.
The red line shows the original path of totality, while the orange line represents the path updated with the new data.
A red arrow indicates a loss in the path of totality, and a green arrow shows a gain.

Eclipse Path and Date Miscalculated
UVM Physicists Show that Totality Will Arrive April 1 and Not Travel Over Vermont
In a stunning and urgent discovery, astronomers at the University of Vermont have determined that a consortium of global space agencies made a fundamental error in their calculation of the path of the upcoming solar eclipse. By failing to account for the time it takes light to travel from the sun, a laser-based model led by the U.S. National Observatory’s Measurement Alignment and Astronomy Ministration, has been shown to be off by seven days and 1,843 miles.
By recalculating the path, the UVM team shows that the shadow of the moon will pass over North America on April 1, not April 8 as previously calculated.
And, instead of traveling from Texas over Vermont, the “path of totality” will travel north until it reaches New Hampshire and curves over the North Pole. “We were amazed and wanted the public and planners to know as soon as possible,” said John Perry, Director of UVM’s Sky Lab. Eclipse watchers should head outside at 12:37pm in the Florida Keys, with darkness arriving in New York City at 2:17pm. The shadow will cross the North Pole at 3:56pm.
“We stand corrected,” said NO-MA'AM’s visualization scientist, Maey B. Wrongge. “Our maps rely on the JPL DE421 ephemeris—but we forgot a basic fact: light must travel 92.5 million miles to get to Earth, rendering our measurements flawed.”
The UVM scientists note that “some dimness” should be visible for 700 miles from the remapped path of totality. “If it remains clear, Vermonters will still be able to see the shadow racing across the White Mountains in New Hampshire,” said Bernard “Chip” Cole, Director of UVM’s NASA-supported Vermont Space Grant Consortium.
