At 5:04 p.m. Tuesday, June 5, the planet Venus will transit, or pass directly in front of, the sun. The transit of Venus is extremely rare, occurring twice in eight-year periods more than 100 years apart. The most recent transit of Venus was in 2004, and it will not happen again until the year 2117.

This event is sponsored by Dyer Observatory and the Radnor Lake State Natural Area.

During the transit, Venus will appear as a small black dot against the disk of the sun. Because the transit will not be visible by looking directly into the sun, Dyer will provide solar telescopes, solar viewing glasses and an LCD TV screen on which to view the event. Astronomers will be on hand to demonstrate other creative ways to view the event and answer questions. In addition, Radnor Lake staff will offer a bird of prey demonstration and rangers will be available to answer questions. Restrooms are available at Dyer.

  • Gates open at 4 p.m. to preview the transit
