The Humanist Society of Greater Phoenix (HSGP) is hosting an astronomy event Tuesday afternoon, 5 June 2012, featuring the Transit of the Sun by Venus.

The location is the Humanist Community Center (HCC) located at 627 W. 8th Street Mesa, AZ. A map of the location is here.

The transit as seen in Phoenix begins a little after 3:00 PM, so arrive early at HCC. The hosts will have a variety of observation methods.

Safety is a primary concern. Please note these warnings from Wikipedia:

The safest way to watch a transit is to observe an image of the Sun projected onto a screen through a telescope, binoculars, pinhole[7] or reflected pinhole.[8] The event can be viewed without magnification using filters specifically designed for this purpose, such as an astronomical solar filter or eclipse viewing glasses coated with a vacuum-deposited layer of chromium. However, the disk of Venus is tiny compared to the sun and not much will be seen. The once-recommended method of using exposed black-and-white film as a filter is not now considered safe, as small imperfections or gaps in the film may permit harmful UV rays to pass through. Observing the Sun directly without appropriate protection can damage or destroy retinal cells, causing temporary or permanent blindness.[9][10][11]
