Public Viewing Events

Solar Eclipse!

Please note, you may check-in for this event as early as 12:00 pm on August 21st in the lobby of the Science and Mathematics Center.

On Monday, August 21st we will be treated to a rare solar eclipse of the Sun beginning at about 1:30 pm and ending at 4:00 pm.  About 65% of the Sun's surface will be covered by the Moon in the sky.  At BSU's Science and Mathematics Center, we will provide multiple ways for you to view the eclipse safely, including access to optical projection systems, solar telescopes with H-alpha or reflective filters, and free eclipse glasses and viewing screens while supplies last.  When you arrive, go to the lobby to pick up safety information and eclipse glasses/viewers first.  Then join us outside on the green or the 5th floor patios for viewing of the Sun.  Professor Doyle will give a talk on the Sun and eclipses in the auditorium from about 1 pm - 2 pm.  This event occurs rain or shine - if it's cloudy, we will stream the eclipse live in the auditorium for all to see.  If you plan to attend this event, please register!  This event is free and open to the public.

Call our hotline at 508-531-DARK a few hours before all events to check whether we will be open (or follow us on Twitter @BSUObservatory, or check our Facebook page at Bridgewater State University Observatory).  You are welcome to park in the West Campus Lot (behind the Science and Mathematics Center).  If full, the nearest lots are the Spring Street lot and Harrington lot.  Once you have parked, use any entrance to enter the science and mathematics center and make your way to the building's central lobby.  There, you will find elevators and stairs to take you to the 5th floor observing decks.  Elevator: Use the right-hand elevator to go all the way to floor 5.  Stairs:  Go all the way up the main staircase to the 4th floor, then turn right and right again.  Enter the first door on your right (it's red).   The staircase here takes you to the 5th floor.

Observatory outreach sessions are free, appropriate for all ages, and made possible by the support of BSU's Physics department as well as CASE, the Dean's Office, Provost's Office, and the Office of External Affairs.

Three of our students have built a 17-inch dobsonian telescope that we can use on our decks.  This telescope is more powerful than the one in the dome!

Solar Eclipse 2017

On Monday, August 21, 2017, a total solar eclipse will be visible through a huge swath of the USA!  Those not in the path of totality will see a partial eclipse, and here in MA we will see the Sun covered nearly 70% by the Moon.  Join us between 1:00 and 4:00 pm at the Science and Mathematics Center for safe eclipse viewing, rain or shine.  More+
