|Venus transit in progress|
Transits of Venus are rare--only eight have occurred since the invention of the telescope. These transits occur in pairs spaced 8 years apart--today's transit was the second member of the pairing. The first of the pair occurred on June 8, 2004. These pairs are separated by periods of approximately 100 years so an observation of a transit of Venus is a once-in-a-lifetime event. (Actually twice-in-a-lifetime). The next transit is due to occur in the year 2117.
My deck is not ideal for solar observations. Around 4:30 PM the Sun dipped below the redwoods so I was able to catch only about an hour and a half of this century's final transit of Venus.
