Welcome to the Theodor Jacobsen Observatory, the second-oldest structure on the campus. Built in 1895, the Observatory, with its 110-year old refracting telescope, is still offering views of the wonders of the Universe. The Observatory is now open to the public every first and third Wednesday, March 1 - November 30.

Here you will find information on opened nights, a history of the telescope, a history of astronomy at the UW, and even an operating manual for the telescope. Come join us in a tour.

Groups Welcome! Reservations strongly recommended for the talks (no reservations needed, though, for just viewing through the ancient 6-inch telescope or touring the rest of the Observatory). We usually get a full house for the talks nearly every open house. Information for making reservations for public visits.)
The talks of the open house season are given by undergraduates at the University of Washington, individuals who are either majoring in physics and astronomy or are in other majors but really enthusiastic about astronomy. The level of the talks varies with the topic. Some are geared more to the younger visitors; most are geared for high school level. Please come and lend your support. By being in the audience you will be taking part in the educational program at the U of W. Observatory is closed until March 4, 2009 (Talk will begin at approximately 7:15 pm)

Making a Difference

You can make a difference in the undergraduate and outreach programs at the U of W. Your donation to the University of Washington "Friends of the Observatory" will go a long way towards maintaining the Observatory and providing the educational materials used there. These funds are also used to support visits by the astronomy undergraduates to local schools and organizations. Besides the Observatory, these undergraduates are active in building a radio observatory on campus, providing K-12 planetarium shows, organizing the Astronomy Club on campus open to ALL undergraduates, as well as working on their individual research projects. Send your check to "Friends of the Observatory," Astronomy Department, Box 351580, University of Washington, Seattle, WA 98195-1580, making sure to state "Friends of the Observatory" in the memo part of the check.

^**Special thanks to Peter Hirtle of the Seattle Astronomical Society for all of his work in restoring the telescope drive and objective lenses, and making the reopening possible. Also special thanks to members of the SAS who continue to support our efforts.
Kudos to the undergraduate astronomy majors who grabbed brooms, vacuums, soap and water to clean the observatory; they have done a wonderful job of making the dome and pillar room presentable again. These students will be hosting the observing nights, including slide shows, tours, and plenty of opportunities to ask questions.
