Washington: A group of astronomy enthusiasts, has partnered with the Venus Transit Project and Esri, a leading geographic information systems company, to create unique smartphone and web apps for the Venus transit.

The web app, created by Astronomers Without Borders, can be accessed from any web browser, and adjusts for mobile as well as desktop platforms. The dynamic app provides several ways for users to learn about the transit and interact with others watching it around the world.

The users can find where and when the transit occurs around the world, see contact timing observations from the VenusTransit smartphone app in near real-time on transit day.

They can even see how they compare to the predicted times, see tweets, photos, and videos of transit of Venus activities on a world map, and share yours through hashtags and key phrases: #tov2012, #venustransit, `Transit of Venus`, and `Venus Transit`, and watch a video explaining the transit, including an animation that shows the whole 6 hour, 40 minute event in one minute.
