The Robert A. Schommer Astronomical Observatory is located in the dome on the roof of the Serin Physics
Laboratories on the corner of Frelinghuysen Road and Allison Road on the Busch Campus of Rutgers, the State
University of New Jersey. Our address is 136 Frelinghuysen Road, Piscataway, NJ and directions to our
building are available. Park in lot 53 (between the building and the street) or lot 53A (about one block
east on the other side of Frelinghuysen Road). Enter the doors on the west end of the building (facing
Allison Road). This places you on the second floor of the building. Take the stairs or the elevator (both of which are on the left side of the
lobby) to the third floor, turn right immediately past the double doors, and enter room 330 on your right.
The observatory itself is located on the 4th floor in room 401, but we ask everyone coming
for our public observing nights to come to room 330 first. We will then guide attendees to the observatory in order to not
overcrowd the dome.
