UI researcher to lecture April 2 on Earth-space dynamics

            Dr. Crockett Grabbe, research scientist in the University of Iowa College of Liberal Arts and Sciences' department of physics and astronomy, will lecture on "The Emerging Dynamic SuperGlobe" at 7 p.m. Tuesday, April 2 in Lecture Room 1 of Van Allen Hall.

            Grabbe's talk, free and open to the public, will include colorful photographs of the Earth's spatial environment, as viewed from both the ground and from spacecraft. He plans to discuss how conditions near the Earth are dynamically linked to the sun, and how humanity's growing dependence on space is creating a "SuperGlobe." Grabbe will discuss the recent development of space weather as a science and how space weather affects commercial space ventures, such as the deployment and operation of satellites that form part of the SuperGlobe.

            Grabbe is a member of the National Speakers Association, the American Physical Society, the American Association of Physics Teachers, the American Geophysical Union, the International Union of Radio Science, and the American Association of Physicists in Medicine.

            Individuals with disabilities are encouraged to attend all UI-sponsored events. Persons with disabilities who require an accommodation in order to participate should contact the department of physics and astronomy at 335-1686.
