Please note: As of April 3, all campus locations have run out of eclipse glasses.

It’s a once-in-a-lifetime event that’ll have you looking up from your phone for at least a couple hours on Monday, April 8. 

McMaster and Hamilton will be among the few places in North America to experience a total solar eclipse. The eclipse will start at 2:03 p.m. and end by 4:30 p.m. The Moon will completely block the Sun for 96 seconds starting at 3:18 p.m., turning mid-afternoon into midnight and filling the sky with stars. 

This’ll be the first total solar eclipse over McMaster since Jan. 24, 1925. The next won’t happen until Oct. 26, 2144. 

“Having a solar eclipse come to you is such an infrequent event,” says assistant professor Robert Cockcroft, who’s also the director of the William J. McCallion Planetarium.  

“Even with all of today’s technology and the fast pace of modern life, we’re still subject to what’s happening in the sky. An eclipse is an amazing reminder for us all.

We’ll be talking about this for a long time after the eclipse. This will be one of those ‘where were you when’ moments.” 

Students and faculty in the Department of Physics & Astronomy are also hosting a series of eclipse talks on campus and in the community, including at Six Nations and Oshweken. 

“I’m pleased that McMaster is using this unique celestial event to take science to local and Indigenous communities,” says Susan Tighe, provost and vice-president (Academic). I’m thankful to the faculty members and students who are volunteering their expertise and time.”
