Henry Smith, 8, of St. Paul was among those gathered on the rooftop of the University of Minnesota's Tate Lab in Minneapolis to see Thursday's partial solar eclipse.

Graduate students organized the viewing party, with lectures and telescopes.

The partial eclipse, which could be seen in most of North America, resulted from the moon orbiting in front of the sun and blocking part of it.

At the peak of the eclipse, as much as 70 percent of the sun was blocked by the moon. The solar event began at about 4:18 and ended at 6:44 p.m.

Here are some more shots of the eclipse shared with the Star Tribune via Twitter on Thursday night:
