2019 Transit of Mercury

Date: November 11, 2019
Time: Morning and early afternoon
Location: Coast-to-coast

On November 11, 2019, Mercury will be passing between the Earth and the Sun. From our view here on Earth, that means we'll see a little black spot slowly crossing the disc of the Sun. However, because Mercury is so small, you won't be able to see it just with solar-filtered eclipse glasses.

You know how you're never supposed to look at the Sun because it'll blind you? That goes doubly for looking at the Sun through any magnifying device, like binoculars or a telescope. However, some binos and scopes have filters on the front that block out enough sunlight that you can safely look through them. If you're going to observe the transit, make sure that you are using solar-filtered binoculars or telescopes, not just any old telescope!

Because of the slight difference in the orbits of Mercury and the Earth, Mercury transits only happen about 13 times per century. The next one isn't until 2032, so you'll want to see this one! Find local RASC events below where RASC members will have solar-filtered telescopes set up so you can see the tiny dot of Mercury traversing the Sun.

Please note that many events below will be weather-dependent. Events may not be run if the weather is cloudy.
