Download the Venus Transit iPhone/iPad App for June 6, 2012

The transit of Venus across the face of the Sun (begins at 06-06-06:12am-2012-varies with location) is the last for this century, which makes it a prominent event. I thought it may just be prominent enough to warrant an app for the iPhone (or iPad), so I did a search and there it was, an app especially made for the June 6, Venus transit!

The Venus Transit app of 2012 boasts of Timer, Simulation, Visibility, and Info tabs. If you click on Simulation,  you will be given Ingress and Egress to choose from. The labels are self-explanatory and tapping on one of them calls up a realistic animation of a magnified Venus either ingressing or egressing with the limb of Sun in the backgound. A timer keeps count and you are given instructions to hit the screen to log the time of contact. But that's only the simulation. The actual logging of contact times is not available until the transit itself, according to the app. Through the app, you can contribute to an experiment where amateur astronomer participants can send in their contact times of the transit.

If you tap the Visibility tab, you will get a map of your location, which also shows the dates and times for the ingress and egress (interior and exterior) of Venus in your area as well as the time for sunrise and sunset. The Info tab gives details of the developers, led by Astronomy Without Borders, with credit to Rikkert Koppes of DDQ Scientific & Educational Apps.

The Venus Transit iPhone App is available for free in the Apple App Store.

UPDATE: During the Venus Transit 2012, an error (possibly due to Internet connectivity or a glitch in the app itself) in the display of the counter prevented the app from being used in the experiment.
