Only the inner planets, Mercury & Venus, can cross the solar disk. Transits of Venus are among the rarest of predictable astronomical phenomena, occurring in a pattern repeating every 243 years, with pairs of transits 8 years apart separated by long gaps of 121.5 years & 105.5 years. Mercury, on the other hand, transits the solar disk approximately 13 times per century. The last transit of Venus occurred in 2012 & the next will occur on December 10th & 11th, 2117. The last transit of Mercury occurred in 2016 & our astronomers viewed that from our SCC Observatory at Sechelt Airport. Mercury is next due to transit the Sun on November 11, 2019 & the Sunshine Coast Astronomy Club will be in Roberts Creek to help people view it. After this, the next Mercury transit isn’t until November 13th, 2032 so you won’t want to miss this.


Only viewers in Ontario, Quebec and Atlantic Canada will be able to view the entire 5 ½ hour event, as the Mercury transit starts at sunrise in that area. Here in BC the transit will be in progress when the Sun comes up: We’ll still be able to view nearly 3 hours of transit. Our astronomers chose a location which would give us the best unobstructed view as the Sun rises to make sure that we capture as much of this transit event as possible. They’ll be setting up at the Roberts Creek pier at sunrise at 7pm with solar scopes. Everyone is welcome to view this event. They’re hoping for clear skies!


A transit of Venus can be viewed with eclipse glasses, but Mercury is too small to view in this fashion. To view a Mercury transit, you’ll need to equip your binoculars or telescope with a front aperture solar filter, use a telescope with a Herschel Wedge and filter, or use a hydrogen alpha telescope designed for solar viewing. Our members will have these solar telescopes set up to allow the public to safely view the Mercury Transit.
