The Venus Transit of 2012 is considered as the rarest predictable astronomical event. It is so rare that one person can only observe it for a maximum of 2 times in his or her lifetime. It occurs when the Sun, the planet Venus, and the Earth are in perfect alignment with each other. As viewed from the Earth, Venus appears as a black dot moving across the disc of the Sun.

Shown below is a brief summary of my observation as part of the Rekindling Venus public viewing and observation held in UP Diliman. The next Venus transit will occur on December 2117.
