The following table shows the schedule and phases of the partial solar eclipse of August 11, 2018 in Canada. For each city we have assigned a time zone which is very precise and it takes into account Daylight Saving Time (if applicable).

Sun Alt.: Excellent  Good  Low  Too low

if present, (r) means the eclipse is in progress at sunrise, while (s) means the eclipse is in progress at sunset.

You can read the table above as follows: On August 11, 2018 in Newfoundland (UTC -7), an eclipse of type partial solar eclipse will start at 06:06(r), the maximum eclipse will occur at 06:06(r) when the Sun reaches an altitud of 0(r)° and azymuth of 064°;this event will come to an end at 06:24:15 and will have a magnitud of 0.129(r) (the magnitude of an eclipse is the ratio of the apparent size of the Moon to the apparent size of the Sun during an eclipse) and an obscurity of 0.056(r) (the fraction of the Sun obscured).

In Newfoundland, for example, due to the small fraction of the Sun obscured by the Moon (5.6%), this eclipse will not be very obvious.

Protect your eyes

Observers must be very careful while viewing the solar eclipse. Our advice is to never look at the Sun with the naked eye.For safety, you must always use sunglasses, telescopes and binoculars with special filters. Never use these equipments without protection as the Sun's ultraviolet and infrared light may harm your eyes or cause blindness if you look at the Sun directly.
