In observance of Global Astronomy Month 2022, the Astronomical League of the Philippines is inviting you to join us this April 23, 2022 (Saturday) at 8:00 PM Philippine Standard Time (UTC + 8:00) for a webinar lecture by Dr. Jay Pasachoff who will talk on “An Antarctic Eclipse: Observations of the December 4, 2021, Total Solar Eclipse from Antarctica”. Dr. Pasachoff is the Field Memorial Professor of Astronomy at Williams College in Williamstown, Massachusetts, USA, and Chair of the International Astronomical Union’s Working Group on Solar Eclipses.

Dr. Jay Pasachoff is the Field Memorial Professor of Astronomy at Williams College in Williamstown, Massachusetts, USA, and Chair of the International Astronomical Union’s Working Group on Solar Eclipses.
A renowned expert on the solar corona and chromosphere, Jay’s research has been sponsored by the National Science Foundation, NASA, and the National Geographic Society. He has led 74 solar eclipse expeditions all over the world (of which 36 are total eclipses) and has published 15 books about the Sun and astronomy, as well as numerous textbooks and articles.
Dr. Jay Pasachoff led the Williams College Eclipse Expedition to observe the December 4, 2021, total solar eclipse from the air, aboard a chartered commercial jetliner, intercepting the Moon’s shadow at 39,000 feet (11,887 meters) near the coast of Antarctica. The eclipsed Sun was visible only 4 degrees above the horizon, with totality lasting 1 minute, 52 seconds.
A second expedition team from Williams College observed the eclipse from the ground, on Antarctica’s Union Glacier.
The goal of the research was to understand how the Sun’s corona is heated to a million degrees, even though the visible surface of the Sun is only about 6,000 degrees Celsius. Somehow, energy is being injected with the help of the Sun’s magnetic field into the corona.
