The 21-inch telescope at Lowell Observatory and historical topics

Lowell's 21-inch telescope has been very busy since it was built in 1953. Here's how we used it:
2,713 Nights and Counting (article from The Lowell Observer, Fall 2004, pdf)
A history of the 21-inch telescope (AAS poster presentation, 2006, pdf)
Harold Johnson at Lowell Observatory: The Age of Photoelectric Astronomy Begins (article from The Lowell Observer, Spring 2008, pdf)
A Century of Uranus Observation at Lowell (article from The Lowell Observer, Fall 2010, pdf),
Bibliography for the 21-inch telescope, 1954-2006 (pdf)


Dark Skies

Dark skies are valuable to everyone with an interest in astronomy. In Flagstaff,
we take this seriously:

Flagstaff's Battle for Dark Skies (prize-winning article from The Griffith Observer, Oct. 2002, by David Portree, pdf)
Wes Lockwood Saves the Universe (prize-winning article from The Griffith Observer, Nov. 2007, by David Portree, pdf)

NAU oral history interview on dark skies


Solar Variability

How the Sun varies and whether this afffects climate has been an enduring theme at Lowell Observatory for 50 years. The question remains controversial today. Our studies never detected solar variability, which we know now to be impossibly small to be detected by ground-based techniques, but the ongoing effort here has led to valuable measurements of planetary and stellar brightness variations. The latest results are found in my bibliography, but here are some earlier milestones.
