Yerkes Observatory, 373 W. Geneva Street, Williams Bay, Wisconsin, will be hosting a public star party Saturday April 9 from 7:00 to 9:00 p.m. Weather permitting, as soon as it gets dark, there will be observing through telescopes. Brilliant Jupiter will be visible with the unaided eye; as viewed through a telescope, it, its four brightest moons and other objects should pose quite a treat.

Even if it is too cloudy to observe, there will be many other things to do including hands-on demonstrations and other activities and tours of the observatory, featuring a look at (but not through) the famous 40-inch Great Refractor within the 90-foot diameter dome.

If you wish, bring your own binoculars, digital camera on a tripod, or telescope. People at Yerkes can help you use them. The Star Party cost is $5 per person or $15 per family. All children must be accompanied by an adult. No pets, please. To sign up, fill out and submit the form below, call 262 245-5555, extension 810, or send email to:
