  • Telescope viewing beginning at 7:40 AM (observatory / rooftop; access from 3rd floor of PHY)
  • Mercury is nearest the centre of the Sun 10:20 AM
  • Transit ends around 1:08 PM

The observatory is hosting a special event for the November 2019 Mercury transit. Multiple telescopes will be set up on the rooftop for safe public viewing of the planet Mercury, crossing directly in front of the Sun. Drop in anytime (or multiple times!) during the morning or early afternoon to view this rare event, and learn what it has to do with figuring out distances in our solar system and discovering new planets in our galaxy.

Note: If the weather turns out to be cloudy, telescope observing will not be possible; special arrangements will apply:

  • If the weather is partly cloudy, we may elect to wait it out
  • In the event of persistent clouds or precipitation, a cancellation notice will be posted to this event listing, as well as the observatory's main webpage
