The next open house will be Friday, June 18th from 9:00 to 11:00PM. If we cancel due to weather, we'll post it here and on the hotline by about 5PM, otherwise it will happen. Directions to the Homewood Campus can be found here.  The observatory is located on the roof of the Bloomberg building, which is #41 on this map.  Parking is available in the upper level of the lot adjacent to Bloomberg (lower level on Tuesday nights).  The lot is marked as #66 on the campus map.  The upper level is reached by driving towards Bldg. #40.  The gates on the top-level parking lot will be raised.  There is no fee for parking in the upper lot.
