The evening sky slowly changes with the seasons. Every month, throughout the year, Yerkes Observatory offers evening observing sessions. June programs will be held on some weeknights and some Saturday nights. Participants aged twelve and up may admire the night sky seen both with the unaided eye and through a large 24-inch diameter reflector.
For JULY dates check again toward the end of June.

June observing dates will run, from 9:30 until 11:00 p.m. if weather permits, and, subject to last-minute cancellation. Scheduled dates are June 4, 5, 14, 15, 22, 25, 26, 27, 28, and 29. The charge is $25 per person, payable the night of the event. Each session is limited to a total of ten, adults and children aged twelve and up. If you wish to attend, you must make an advanced reservation by calling Richard Dreiser at 262 245-5555, extension 880, or, by sending an email request to: rdd@yerkes.uchicago.edu

Participants begin outside. From the dark confines of Yerkes, one may get superb views of planets, constellations, hundreds of stars, occasional sporadic meteor streaks, the Milky Way, and, the bright, moving International Space Station. Bring a pair of binoculars to enhance your stargazing experience.

Afterwards, we enter the building and climb 39-steps of a spiral staircase up into the northeast tower. Here we will observe through the 24-inch diameter reflector brilliant Saturn and its moons, the Moon whenever possible, and, globular clusters and galaxies, invisible to the unaided eye.

Participants should bring jackets or sweatshirts as we will be spending time outside and within an unheated dome, and, even summer nights may be chilly! Please wear sensible shoes: no high heels or flip-flops, please.
