Watching the Transit of Venus 2012 in Dolores Park (San Francisco)
View my other photos of the Transit of Venus. This is a rare astronomical event: The next time this will happen is in year 2117.
A welding glass filter, Shade 14 or 16, works well to watch the sun with the naked eyes, e.g. during partial eclipses.
Unclassified photos taken in San Francisco Bay Area.
