WILLIAMSTOWN, Mass., July 13, 2018— Jay Pasachoff, professor of astronomy at Williams College and Chair of the International Astronomical Union’s Working Group on Solar Eclipses, observed the second solar eclipse of the year from the grounds of the Mt. Pleasant Radio Observatory of the University of Tasmania in Australia. It was the 68th solar eclipse that he had observed.

Pasachoff reports that the partial eclipse lasted 64 minutes and that weather conditions were ideal, with clear skies virtually the entire duration of the eclipse. Even when clouds appeared in the final minutes of the eclipse, the sun was always visible.

According to Pasachoff, this solar eclipse was visible only from Antarctica and southernmost parts of Australia, especially Tasmania, where 10 percent of the solar disk was covered at maximum.

Pasachoff captured images of the eclipse using a Nikon D600 and 500-mm f/8 Nikkor lens and a Thousand Oaks Optical filter as well as with a Nikon D7100 and 400 mm Nikkor lens with a Questar filter.

There are two more partial solar eclipses—August 11, 2018, and January 6, 2019—before the next total solar eclipse, which Pasachoff will observe from Chile on July 2, 2019, now less than a year away.
