Ye Stars! Which are the poetry of heaven
– Lord Byron (1788-1824)

To witness a total eclipse of the Sun is a privilege that comes to but few people.
Once seen, however, it is a phenomenon never to be forgotten

– Isabel M. Lewis ("A Handbook of Solar Eclipses", 1924)

See Gainesville Sun article about these unique tours (pdf document).

Tours he has helped organize and escort include trips to the Caribbean (1998), Africa (2001) and Australia (2002) to observe eclipses of the Sun, Italy/Greece (2004) to observe the transit of Venus, and an unusual hybrid solar eclipse (2005) from the South Pacific on Radisson's Ms Paul Gauguin. (Dr. Cohen has been to ten total and annular solar eclipses.) In September 2005 he helped plan lead a unique tour of Arizona to see the astronomy, archaeology and geology of the Grand Canyon State.

In 2006 he helped lead a fascinating eclipse tour to Egypt and the Nile for the March 29 total solar eclipse. And in 2009 he helped escort an exceptional and successful tour to China for the July 22 total eclipse of the Sun (longest duration of the 21st Century). An eclipse composite appears here.

See his article, "When the Sun Goes Dark," (Senior Times Magazine, May 2009, pp. 27).

Norway Northern Lights Cruise 2010

Ever see the magnificent, eerie and illusive Northern Lights (Aurora Borealis)? In 2010 March he helped escort a group on one of the most beautiful cruises in the world to above the Arctic Circle along the dramatic, western Norwegian coastline on a Norway Northern Lights Cruise. See some aurora borealis photos taken by Dr. Cohen on this successful cruise.

(And it wasn't easy taking these photos from a rolling ship with frigid winds blowing!)
