A partial solar eclipse will occur on Sunday evening. A partial eclipse is one in which only the outer ring of the moon's shadow (the penumbral shadow) traverses the Earth, blocking a portion of the sun. Across Wisconsin, the moon will block 50% to 60% of the sun about an hour before sunset. The table below lists a few details about the eclipse for Green Bay and Wausau.
|Start Time||7:20 PM||7:19 PM|
|Duration||59 minutes||1 hour 7 minutes|
|Sunset||8:19 PM||8:27 PM|

What about the weather forecast? A cold front will be moving across Wisconsin on Sunday afternoon and evening, so clouds and scattered showers or storms may obscure our view.
While Wisconsin will only experience a partial solar eclipse, certain areas in the southwestern and western United States (highlighted on the map below) will experience an annular eclipse. An annular eclipse occurs when the moon moves directly between the Earth and the sun. Since the moon is slightly more distant from the Earth than on average, there will still be a ring of light, or a "ring of fire", around the silhouette of the moon. In a total eclipse, the ring of fire is not visible.
