'Earth's dynamic neighborhood' is subject of public lecture April 24

IOWA CITY, Iowa - "Earth's Dynamic Neighborhood" will be the subject of a free, public lecture at 7 p.m. Monday, April 24 in Lecture Room 1 of Van Allen Hall on the University of Iowa campus. Dr. Crockett Grabbe, research scientist in the UI department of physics and astronomy, will present the lecture.

Grabbe's talk includes colorful photographs of the sun-Earth environment from both the ground and spacecraft. He will discuss how conditions on Earth are dynamically linked to the sun and solar winds and how solar winds interact with the Earth's magnetic field to influence the Earth's environment. Grabbe will also discuss the recent development of space weather as a science and how space weather affects commercial space ventures, including the deployment of satellites.

Grabbe, who has disabilities from both a pituitary tumor and a cerebral hemorrhage, has spoken to public audiences in the United States and Europe. He is a member of the National Speakers Association and six scientific organizations.
