Join members of the Royal Astronomical Society of Canada (RASC) Regina Centre to view the planet Mercury transit across the face of the Sun.

This is your last chance to see this until 2032!

This event is weather dependent.


A Transit of Mercury occurs when the orbits of Mercury and the Earth align such that we can see Mercury cross the face of the Sun. This is a relatively rare occurrence and the next Transit of Mercury does not occur until 2032 so you will not want to miss this event.

In the west of Canada, the Transit begins before the Sun has risen so we will gather at sunrise to catch the Transit in progress. Assuming the sky is clear, we will be able to see Mercury slowly move across the face of the Sun until just after noon. You can join us at any time from 8:05 a.m. until 12:04 p.m. when the Transit will be complete from our location in Regina. Make sure to dress warmly as it is likely to be a cold fall morning. We will have to cancel viewing if the sky is overcast or there is precipitation.

Viewing a Transit of Mercury requires the use of specially filtered telescopes that RASC Regina will have at the event. You should never attempt to look at the Sun directly without the appropriate equipment as it could cause permanent eye damage.
