Please remember to always carefully and safely observe the sun! Welcome all to an afternoon of solar observing! We meet outside, from 12-2pm, near the Hardin Planetarium at the intersection of State St and College Heights Blvd. We utilize a Sunspotter (to show mass groups the sun's sunspots and to teach geometric astronomy), 9.25" Celestron NexStar with a solar filter (to show fine details such as flares and prominences), and a Coronado PST (the included Hydrogen Alpha filter really helps display the flares). Sometimes, we'll pass out solar viewing glasses. And sometimes, we'll have videos inside the planetarium dome showcasing different wavelengths of the sun.
