Rooftop Observatory Solar Image

This page shows the latest image of the sun taken by the department's 14-inch Celestron telescope, located on the rooftop of the Cahill Center on the Caltech campus. Starting at approximately 3:07pm on June 5, 2012, the planet Venus will be seen to transit the face of the Sun. This web page will refresh periodically to show the disk of Venus superposed on the Sun, until the telescope loses sight of the Sun some time after 5:00pm.
