Phillips Auditorium is located at the 60 Garden Street facility of the Harvard-Smithsonian Center for Astrophysics, near the Harvard and Porter Square stations on the MBTA's red line. Directions to the CfA are available here, and a map of the building is available here.


All cars parked in Observatory lots at 60 Garden Street during business hours (8:30 a.m. - 5 p.m.) must display a parking permit. You may purchase parking permits at the CfA on the day of the meeting, or online prior to the meeting. Permits are subject to availability and are $13 for an 8 hour permit, $8 for a 4 hour permit, and $4 for a 2 hour permit. We recommend arriving early, and carpooling or taking mass transit if possible.

Day of Meeting: Parking permits can be obtained at the Harvard College Observatory (HCO) Administrative Office, located in B-115. There will be signs posted to aid you in finding your way to the HCO office. At the HCO office you will need to pay by cash or check (no credit cards allowed). You will then need to place the permit in your car.

Online: Full-day parking permits can be purchased online prior to the meeting with a credit card. On the left side of the page, click "Online Tools." Click "One-Day Online Permit." At the bottom of the page, click "Visitor" if you are not a Harvard employee. Visitors must register, so click on "Click Here to Register" and fill out log-in information and your personal profile. Then follow the directions on the screen. You will need to choose "Observatory" as the department and use 2018 as the code. Once you completed the process of purchasing the permit online, print out a copy of the receipt and place it on your dashboard.


The New England Space Science Consortium (NESSC) includes solar, space, and heliospheric physicists from a variety of institutions including Boston College, Boston University, the Harvard-Smithsonian Center for Astrophysics, MIT, and the University of New Hampshire. Workshops are held several times per year on topics of interest to the local space science community.
