Video: Variable Stars with John Percy

John Percy just celebrated his 60th year as a member of the RASC, Toronto Centre! Congratulations, John! In addition, he is Professor Emeritus at the University of Toronto Department of Astronomy and Astrophysics. And it would be remiss to not mention that John is also a member of the American Association of Variable Star Observers (AAVSO). In this presentation, John honours us with his in-depth knowledge and passion: variable stars. He gave his talk at the Recreational Astronomy Night online edition on July 7, 2021.
