"The Unexpected Shadow of the Total Solar Eclipse"

Viewers of the recent solar eclipse in Montreal were treated to two surprising phenomena: a sharp shadow caused by a passing airplane just after the eclipse concluded, and a spectacular halo around the partially eclipsed sun. The sharpness of the airplane's contrail shadow was accentuated by the eclipse, while the halo around the sun was unrelated to the eclipse and is a common optical illusion created by ice crystals in the upper atmosphere. These displays can occur frequently and are not limited to polar regions, making them a fascinating phenomenon to watch out for.

"Maximizing Your Visual Experience: The Best Way to Watch the 2024 Solar Eclipse"

During Monday's solar eclipse, people along the path of totality can expect to see unusual visual effects, including changes in how they perceive colors such as red and green due to the Purkinje effect. As the moon blocks the sun, the dimming light will cause colors with longer wavelengths, like red, to appear darker, while shorter blue-green wavelengths will stand out. Other phenomena to anticipate include sharper shadows, crescent-shaped projections of the sun's image through tree gaps, and shadow bands.
