Solar Eclipse: Experts Had The Map Of Totality Wrong, See Updates​


There has been an update on next week’s solar eclipse path of totality map that will affect people living on the very edge of the previous map.

This weekend, experts announced that the viewing area on April, 8 is slightly narrower than the 115-mile-wide path scientists previously calculated. So cities such as Fort Wayne, IN, and Denton, TX, may not get a full show as they had expected.

“By accounting for the topography of both the moon and the Earth, precise eclipse prediction has brought new attention to a tiny but real uncertainty about the size of the Sun,” said NASA Heliophysics Editorial Lead Abbey Interrante, per WKRN.

The reason the sun’s size factors in is that the shadow produced by the moon shrinks as the sun’s size grows. Scientists used a smaller sun size in the former calculation.

John Irwin, an eclipse calculator, noticed the problem recently. He released an updated solar eclipse path of totality map, which you can find here.

Eclipse Calculators Had Been Using The Same Solar Radius Since The Late 1800s​

One of Irwin’s collaborators, Luca Quaglia, told Forbes that the computer had plugged in the numbers and it used a solar radius of 959.63 arc seconds, which is the same number scientists had been using since the late 1800s. According to Quaglia, “measurements and observations” from the last decade have shown that value to be “slightly too small.”

1% increase in the size of the Sun? I wonder if that means we need to change the Global Warming Calculations too
