The meeting will be held in the Pratt Room. The main entrance to the Center for Astrophysics, HarvardSmithsonian is up the driveway opposite Linnean Street (by the Radcliffe Quadrangle and just past the Radcliffe Quad Athletic Center). Go up the driveway and the large 3 story building is the Perkin Laboratory for Astrophysics. The Pratt Conference Room is on the ground floor of Perkin. Enter the building, the Library should be on your left. There is a black doorway just in front of you (right opposite the entrance) which leads to a stairwell. Go down one flight to the G level, turn right as you leave the stairwell and Pratt is at the end of a short corridor. Please join us for a pre-meeting dinner discussion at House of Chang, 282 Concord Ave, Cambridge, MA at 6:00pm before the meeting.
