Glenn Schneider (Steward Observatory, The University of Arizona) — Self-Confessed Umbraphile

Glenn Schneider is an UMBRAPHILE. Literally a "shadow lover", but properly applied, one who is addicted to the glory and majesty of total solar eclipses. Those who have basked in the moon's shadow will understand without further explanation. Those who have not may have difficulty in understanding that umbraphillia is not only an addiction, but an affliction, and a way of life. The real raison d' etre for many of us. The more common and prolific term "solar eclipse chaser" is nearly synonymous, but somehow does not convey the depth of commitment to this lifelong endeavor. Once every 16 months, or so, (on average) umbraphiles will drop whatever they are doing and trek by plain, ship, train, foot, and camel-back to gather along a narrow strip in some remote God- forsaken corner of the globe defined by the inexorable laws of celestial mechanics. Newtonian physics heeds no national boundaries, and neither do umbraphiles. Wherever the solar photosphere will be extincted, enshrouded by the ashen lunar disk, umbraphiles will revel in the quasi-twilight darkness.

Glenn has basked in the moon's umbral shadow thirty four times since seeing his first Total Solar Eclipse in 1970. Remaining mobile and aggressively seeking clear skies, he has suffered the trauma of being clouded out "only" three times -- a TSE track record (no pun intended), of 92.6% by time, 91.4% by number.

Air (a), Land (b), and Sea (c).  Most recently (2019) Glenn enjoyed a prolonged 8m 27s of totality from 1,100 km north of Easter Island 41,000 ft above sea level from aBoeing 787-9 sircraft, and most immediately prior (2017) 2m 05s from on US soil during the "All American Eclipse" from Oregon State University's Central Oregon Agricultural Research Station. Recently earlier (2016) Glenn basked in 3m 05s of totality from the southern shore of Tidore island, following 3m 39s of totality (2015) from a Boeing 737-800 aircraft at 35,000 ft above the Norwegian sea northwest of the Faroe islands, after (2013) 10.7s of totality with the late afternoon Sun 12° above the horizon and ~ 300 ft over the cloud tops from 10,800 ft above northern Kenya in a Cessna 208 B aircraft. This followed his previous TSE with the Sun 13° above the morning horizon in total eclipse for 2m 02s from a cow paddock 65 km NW of Mt. Carbine, Australia. Prior, his EFLIGHT 2010 set a civil aviation record-breaking 9m 23s of totality (more than nature ever intended!) from the flight deck of an Airbus A319 aircraft over the South Pacific, after thwarting, partially, the clouds over Wuhan, China in 2009.  Prior, Glenn had the privilege, and joy, of being immersed in the Moon's umbral shadow for his:  (a) 27th time -- from the flight deck of an AirBerlin/LTU Airbus 330-200 < 7 degrees from the North Pole;  (b) 26th -- from Side, Turkey (for the first time, though,  from the luxurious grounds of a 5-star hotel on centerline!); (c) 25th --  observing a 32s totality at sea level while traveling at Mach 0.02.  He would love to hear from other eclipse chasers to share their experiences as well.  More?  See:
