NASHVILLE, Tenn. (WKRN) – We’re just under two weeks away from the total solar eclipse and there are a lot of scientific terms that will be used to describe what you see.
News 2’s eclipse expert, Janet Ivey of Janet’s Planet, compiled a list of words commonly used when talking about a total solar eclipse so you’ll be able to confidently speak about everything eclipse.
Umbra: The darkest part of the moon’s shadow.
Penumbra: The pale or lighter part of the moon’s shadow.
Bailey’s Beads: The small bits of sunlight peaking between the moon’s rugged edges revealing beads of light, resembling a diamond ring, in the seconds before and after totality during a total solar eclipse.
Corona: The Sun’s outer atmosphere and visible during total eclipses as a pearly white crown surrounding the Sun.
First Contact: The instant when the partial phase of an eclipse begins.
Second Contact: The instant when the total phase of an eclipse begins.
Third Contact: The instant when the total phase of an eclipse ends.
Fourth Contact: The instant when the partial phase of an eclipse ends.
Partial Eclipse: When the moon appears to block part (but not all) of the Sun’s disk.
Path of Totality: The trail the Moon’s umbral shadow races across during a total solar eclipse.
Total Solar Eclipse: Occurs when the Sun’s disk is completely blocked by the moon. The Sun’s faint corona is then safely revealed to the naked eye.
