2015: Svalbard Eclipse

Our team in Svalbard included
Jay Pasachoff/Naomi Pasachoff (Williams College)
Allison Carter (Williams College ’16)
Vojtech Rusin (Tatranska Lomnica Obs., Slovakia)
Ron Dantowitz (Clay Center Observatory, Brookline, MA)
Aris Voulgaris (Aristotle U, Thessaloniki, Greece)
John Seiradakis (Aristotle U, Thessaloniki, Greece)
Michael Zeiler (eclipse-maps.com; Santa Fe, NM)
Michael Kentrianakis (New York City)
Edw. Ginsberg (U. Mass. Boston)
Rob Lucas/Helen Robinson (Sydney, Australia)
and we are coordinating for data display and reduction, and accessing space results, with
Dan Seaton ’01 (SWAP/Royal Observatory of Belgium)
Pavlos Gaintatzis
Wendy Carlos
Glenn Schneider

We were supported by a grant from the Committee for Research and Exploration of the National Geographic Society, with additional support from Williams College.

A composite image from the Williams College expedition to Svalbard for the March 20, 2015, total solar eclipse fills in the gap between an ultraviolet image of million-degree gas in the solar corona from the European Space Agency/Royal Observatory Belgium’s SWAP (Sun Watcher with Active Pixels) spacecraft (17.4 nm wavelength in the extreme ultraviolet) and the U.S. Naval Research Laboratory’s LASCO (Large Angle Spectrometric Coronagraph) C2 on ESA’s Solar and Heliospheric Observatory (SOHO).  The eclipse image was given a bluish tinge to make it possible to distinguish it from the space images.  The corona showed the streamers at a wide range of latitudes typical of solar maximum.  The expedition to Svalbard was supported by a grant from the National Geographic Society’s Committee for Research and Exploration.

The following is a blended image (made by Wendy Carlos) of eclipse images by Jay Pasachoff and Allison Carter.  It is optimized to match a visual view over a wide dynamic range.

The following is an image processed by Ron Dantowitz of some of the images he took jointly with Jay Pasachoff.  It is optimized for a higher contrast than visual range to bring out overlapping coronal streamers.

Other scientists in the expedition included Ronald Dantowitz of the Clay Center Observatory in Brookline, Massachusetts; Vojtech Rusin of the Tatranska Lomnica Solar Observatory in Slovakia; Aristeidis Voulgaris and John Seiradakis of the Aristotle University in Thessaloniki, Greece; and Robert Lucas from Sydney, Australia.  Amateur astronomer Michael Kentrianakis of New York City and eclipse map-maker Michael Zeiler were also part of the team.
