LOCATION: Prescott Public Library, Founder’s Suite
SPEAKER: Carl Hergenrother, University of Arizona, staff scientist at the University of Arizona Lunar and Planetary Lab
SUMMARY: Carl Hergenrother, member of the OSIRIS-REx science and operations team, talks about observing comets and asteroids with small telescopes. Carl’s work has included helping Steve and Tim Spahr conduct a photographic survey for new asteroids and comets called the Bigelow Sky Survey, which was the precursor to the highly productive, and still active, CCD-based Catalina Sky Survey. Carl’s current research also includes telescopic measurements of the activity level of comets and rotation and color photometry of near-Earth asteroids.
