The gods evidently see more portent in the Senate debate; they are throwing a pre-game eclipse party! The new moon's shadow hits Kamchatka at their Friday dawn, then slides across Alaska, Canada, the Lower 48, and Mexico throughout our Thursday.

According to the United States Naval Observatory, the partial eclipse begins in Vermillion at 4:23 p.m. Central, and maxes out just after 5:36 p.m., when the moon will obscure just about 49% of the sun. The moon will still be taking a bite out of the sun when the sun sets at 6:33 p.m. Predicted cloud cover for Vermillion tomorrow p.m.: 14%–17%.

Out in Spearfish, the eclipse begins just before 3:10 p.m. Mountain, just in time for the kids to get out of school and see all the freaky shadow effects. Spearfish eclipse max is at 4:28 p.m. Mountain with 53% solar obscuration. The moon scoots past the sun completely at 5:38, about 22 minutes before Spearfish sunset. Predicted cloud cover: 28%–33%.

Go see the eclipse (but how many times do we have to tell you: don't look directly at the sun!), then see who eclipses whom at the SDPB Senate debate!
