This is an image of the Sun during an annular eclipse on May 20, 2012. Three groups of large sunspots were visible on the surface of the Sun prior to the eclipse. Additional smaller sunspots were also visible, and one of them is visible at the bottom of the annular ring of the Sun in this image. During the annular eclipse, the sky became sufficiently dark that the planet Venus became visible during the eclipse. Venus was close to the Sun on its way to a June 5, 2012 transit across the face of Sun. The temperature dropped noticeably during the eclipse.
This image was taken with a Canon EOS Digital Rebel SLR camera on a Takahashi FS-78 refractor and Thousand Oaks Optical Type 2+ solar filter, all carried by a modified Takahashi EM-10 mount. This image was taken from a location near Reno, Nevada.
