Video: Observing Report on "A Sunset"

On March 21, 2018, Ron Macnaughton gave a report on his observations of a simple sunset. In the process, he enlightened his audience on a phenomenon that occurs in the sky on the opposite side of the setting sun that most of us might not be aware of. He gave his presentation at the Royal Astronomical Society of Canada - Toronto Centre's Recreational Astronomy Night meeting held at the Ontario Science Centre.
