Transit of Mars
now browsing by tag
At 4:44 UTC time, the fourth and last contact of the Transit of Venus happened. My son and I watched it via livestreaming at the Exploratorium website. We could have joined also the event hosted by the College of Science Amphitheater, UP Diliman, Quezon City on June 6, 2012 at 730am. However, we did not feel like going out so we stayed home.
At about 10:30, Special Education Philippines saw a post from my sister about a livestreaming site where you can watch the Transit of Venus 2012 in real time. And that is how at the nick of time we were able to see the third and fourth contact of the Transit of Venus 2012. There is also a commentary every 30 minutes about the Transit of Venus and some trivia why it is important to witness this transit.
I am sure it would be different to be in the field with your family and friends looking at the telescope watching the Transit of Venus. The commentator in the Exploratarium said that a lot of people must be doing the same thing. However, he warned us not to look at the sun directly and to use the correct filters while viewing the transit. I heard him mention three different filters they used to view the transit namely: whitelight, halogen alpha and calcium filter. Upon futher investigation, I researched three common filters used by astronomers in viewing the sun.
Why use filters?
