Solar Observing with the Northwest Suburban Astronomers

  • Sillman Nature Center 33 West Penny Road South Barrington, IL, 60010 United States (map)

Join the Northwest Suburban Astronomers and observe our nearest star with special telescopes and filters. See sunspots and solar prominences in remarkable detail! This will be a fun and safe activity for the entire family. After observing the sun, take a hike on your own or join a walk led by Stillman’s naturalist.

If you like, bring a dish and join us for a potluck picnic. Remember to call Stillman at 847-428-OWLS (6957) and let them know if you’re coming. If the weather is iffy, call Stillman for an update before making the trip.
