A solar eclipse occurs when the Moon places itself directly between the Earth and the Sun, hiding it in part or in whole. In southern Canada, the eclipse will be partial, that is, the Sun will not be completely hidden. In Montreal, the eclipse will already have started at sunrise, around 5:07 am, and it will peak at 5:39 am At that time, 79% of the Sun’s surface will be obscured by the Moon. An hour later, at 6:39 a.m., the eclipse will be over.
“Solar eclipses, even partial ones, are rare astronomical phenomena because they are only visible in a limited region of the globe. It is truly a spectacle worth admiring! ” indicates Frédérique Baron, astrophysicist at the University of Montreal.
This map shows the different areas where the June 10 eclipse will be visible in Quebec: in the dark blue region, the eclipse will be annular, while, in the green regions and yellow regions, it will be partial. In Montreal, which is in the yellow zone, the sun will already rise eclipsed.

It is in a corridor that stretches from northern Ontario and Quebec to Siberia via Nunavut that the spectacle will be the most impressive, because the silhouette of the Moon will come to be placed directly on the Sun, hiding its entire center and leaving only a ring of the Sun visible.
“It is the first time that such an eclipse – an eclipse annular – will be observed in the skies of Quebec since 1930! ” adds Nathalie Ouellette, astrophysicist at the University of Montreal and coordinator of the Institute for Research on Exoplanets at UdeM (iREx).
Want to admire the eclipse?
The iREx and its partners are participating in several initiatives to encourage Quebecers to get up early on June 10 to enjoy this rare event!
Warning! You should never observe the Sun directly, during an eclipse or at any other time. Even partially eclipsed, it still represents a serious danger to the retina.
“To observe the Sun in a safe way, you have to use a solar filter that allows only a tiny fraction of the light to pass through, complying with the standard. [ISO 12312-2: 2015], or even follow the show indirectly, by a projection mechanism, ”explains astrophysicist Frédérique Baron.
Sun filters distributed free of charge

In Montreal, more than 4,000 solar filters will be distributed free of charge in municipal libraries on the island of Montreal. On the UdeM side, to get an information sheet with a detachable filter that allows you to look at the Sun in complete safety, go to the Science Library on the MIL campus or to the Mathematics and Computer Library of the André-Aisenstadt pavilion. Most of these places will be distributing them from 1is June. Hurry, quantities are limited!
The Eclipse Challenge: another way to observe this astronomical phenomenon
Even without a solar filter, it is possible to follow the eclipse in a safe way by watching a projection of the Sun, which can be created very easily, as explained on the Web page of the Eclipse Challenge, launched by the organization À la discovery of the Universe.
“One might think that it is complicated to create such a projection system, but it is not! says Marie-Eve Naud, astrophysicist at iREx and project manager for Discovering the Universe. We can make one in less than a minute with two sheets and a sharp object like a sharp pencil, or even without any material at all, using our hands! ”
The podcast “Les astrophysiciennes” accompanies you during the eclipse
On the day of the observation, go – ideally before sunrise – to a place where the horizon is clear to the east-northeast. To accompany your observations, a special episode of the podcast Astrophysicists will be online very early in the morning of June 10.
You will meet there the iREx astrophysicists Frédérique Baron and Nathalie Ouellette as well as collaborators from Space for Life and Discovering the Universe to learn more about solar eclipses.
The invitation is out! On the morning of June 10, grab your sunscreen or projection device, listen Astrophysicists and go out and see the eclipse!
