Transit of Venus Tomorrow




Just a reminder, gentlemen, that tomorrow will be the 2nd and last opportunity of our lifetimes to view a transit of Venus.  The transit will begin at 6:04 EDT, and will be visible through sunset tomorrow.  We will not have the opportunity to see the entire phenomenon.

In case the weather doesn't cooperate, which is looking likely at this point, here are a few helpful websites.

Sky & Telescope - Transit Article and Viewing Tips

W.M. Keck Observatory - Live Web Stream for Transit  Click on the homepage's link to the live stream of the transit tomorrow.

NASA - Official Transit of Venus Webpage  There are links to multiple live streams of the transit.

If you don't have safe viewing equipment, consider making a pinhole camera for safely viewing the transit tomorrow.  Pinhole Camera Directions (Latin = Camera Obscura)  ALWAYS BE OVERLY CAUTIOUS ABOUT OBSERVING THE SUN; YOU CAN QUICKLY DO PERMANENT DAMAGE TO YOUR EYES!


To build the simplest pinhole camera of all, you need two sheets of heavy paper.  Poke a pinhole in one sheet (or use a piece of carboard and some aluminum foil).  Use the 2nd sheet of white paper as your "projection screen."  Change the distance between the two to bring the image into focus.  You can use your pinhole camera to make cool images of many things in nature, including trees and other shadows.

In addition, if you have a pair of binoculars, you can project an image of the sun on a sheet of paper.  NEVER LOOK DIRECTLY AT THE SUN THROUGH BINOCULARS OR A TELESCOPE WITHOUT THE PROPER FILTERS.

Good luck!
