Take a look at the sun through special solar telescopes during the fourth annual International SUNday at the Liberty Bank Alton Amphitheater!

Members of several local astronomical organizations will be on hand to celebrate the Summer Solstice. There will be food vendors on hand. Representatives will also share information about the sun, our nearest star in the Solar System. Amateur astronomers will provide their own optical equipment to safely view the sun including hydrogen, alpha, calcium and white light views.
