|Annular Solar Eclipse of May 20, 2012
On May 20, 2012, the moon passed between the earth and the sun, casting a shadow that began in the early morning in southern China, crossed
Tokyo Japan, sped through the Pacific Ocean, and entered the western US in the afternoon. Throughout this entire course, one of the best
locations to view the eclipse was in southern Utah because of the unique prospects for clear skies. The partial eclipse began at 6:24 PM (see image
below), and reached maximum at 7:35 PM about an hour before sunset (shown above), 11 degrees above the horizon. The moonâ€™s shadow
then began to leave the sun, with the final partial phase descending behind the mountains at sunset.
I obtained all photos on this page with a Canon 60Da camera through a Lunt 60 mm solar telescope. The ring of fire of the recent annular eclipse
takes on new meaning when photographed with the new generation of solar telescopes that have been developed for the amateur astronomer.
These telescopes transmit only a narrow wavelength of visible light called Hydrogen Alpha, that helps reveal solar prominences around the edge of
the sun. When the moon covers up most of the sun's disc during an annular eclipse, this ring of fire becomes even more evident.
