Partial Solar Eclipse Observed on Big Island

July 22, 2009

On July 22, 2209, the longest total solar eclipse of the 21st century was visible in Asia. The Japanese version of the National Astronomical Observatory of Japan’s web pages shows some impressive images of this event.

Only a partial solar eclipse could be observed in Hawaii in the west sky just before 6 p.m. on July 21st. Dr. Tetsuharu Fuse, an astronomer at Subaru Telescope, commented, “Since this phase of the eclipse was smaller when it passed over Hawaii, the sky did not darken and the exterior brightness of the sun and the scene did not appear changed to the naked eye.”
