On Monday night, Jeff and I brought a small telescope from the Columbia astronomy department to the corner of Powell Boulevard & 125th Street. After setting up the 'scope next to the statue of Adam Clayton Powell Jr., we invited everyone walking by to stop and have a look at the first-quarter Moon and Jupiter. It was the third time this year that Columbia astronomers have coordinated "sidewalk astronomy" for our neighboring community. As before, none of the hundred or so people who stopped to take in the view regretted the interruption. Our next sidewalk astronomy attempt will be November 23-24.
