In Toronto, where the next total solar eclipse will not be seen until 2144, clouds obscured the sun for the duration of the eclipse. But when the time of total solar eclipse (99.7 percent) came, it became completely dark and very cold.

At Toronto's York University, where thousands of students had gathered at the top of their science blocks to witness the once-in-a-lifetime event, the lights went off during a short period of total eclipse at 3.19 pm on Monday.

Canada's top astronomer and former York University professor Paul Delaney, who was on hand to explain the significance of this solar eclipse, said, "From a science perspective, when you're blocking the Sun, you're disrupting the dynamics in the atmosphere." Are changing." And the atmosphere reacts very differently during a total eclipse.Radiowave propagation is affected. NASA is launching its sounding rockets from Niagara Falls into the upper atmosphere to monitor changes in radiation from the atmosphere."

He said, "This total solar eclipse has allowed us to study the diameter of the Sun which has recently come under considerable scrutiny because scientists think it is changing. This eclipse is an opportunity to measure the diameter .They are looking at the sun's corona and corona."The sphere. It will tell us about the magnetic field around the Sun. We will get a lot of information from this solar eclipse."

The last total solar eclipse in Toronto occurred in 1925. “It was cloudy in Toronto in 1925.Scientists at the University of Toronto tried to measure changes in the intensity of light coming from the Sun that day. A total solar eclipse followed soon after. The total solar eclipse of 1919, when British astronomer Arthur Eddington verified Einstein's famous theory of relativity,'' he said.

A total solar eclipse occurs somewhere around the world every 18 months, but North America's next total solar eclipse won't occur until August 23, 2044.
