Ryerson Wednesdays: Public observing hours in fall quarter and winter quarter are 7:30-9:30 PM and 8:30-10:30 PM in spring quarter. Ryerson Wednesday will be cancelled if the sky is cloudy. Take the main Ryerson stairs to the third floor, turn right, and continue up the spiral staircase to the roof.
Special Events: We visit Yerkes Observatory in Wisconsin at least once every quarter. During spring quarter we
Note: If the door to Ryerson is locked, you can enter through the south door of Eckhart. Go to the second floor and cross over to Ryerson from there. If you have trouble, call +1-773-702-7625 (2-7625 from any campus phone) which rings in the office and the dome. A map of campus with Ryerson Physical Laboratory marked can be found here.
Its beginnings lost in the misty shrouds of history, the observatory has existed since 1900 and the RAS as a student organization at the University of Chicago since 1952 (when our logbooks began). We operate a 107 year-old 6.25-inch Petitdidier refractor, along with a modern 10-inch (250mm) f/6 Newtonian, both mounted on a hundred and ten year old Warner & Swasey mount. The mount is painted blue, the same color as the great Yerkes 40 inch refractor mount. Carl Sagan was a member a long, long time ago. We're prone to holding meetings every week and giving some sort of lecture on topics usually only remotely related to astronomy. More history here.
The RAS has a tradition of requesting funding from Annual Allocations for ambitious projects. Here are items we've requested in recent years:

Look into our old logbooks for an entry about activities in the RAS office. Here's another entry by this member regarding Chicago temperatures. Following his example, this shaky phrase still appears in modern logbooks, especially in the month of January.
