The monthly meeting of the Lincoln Orbit Earth Science Society rock
and mineral club will be held on January 28th starting at 6:30. Dr. Carl Wenning, a well known central Illinois astronomy educator, will be giving a talk titled - Fire and Ice: The Pending Collapse of Earth's Magnetic Field.
Earth's magnetic field last reversed itself 780,000 years ago, and the next reversal is long overdue. Earth's magnetic field is weakening. Should Earth's magnetic field entirely collapse during the next reversal, Earthlings will be subject to dire consequences from the Sun's coronal mass ejections and deep space cosmic rays. What might we expect in future year? In an attempt to answer this question, the speaker will tie together such diverse topics as the sun, the planets of the inner solar system, Earth's magnetic field, the auroras, plate tectonics, paleomagnetism, African tribal customs, and his recent visit to Iceland's Mid-Atlantic rift valley.
The meeting will be held downstairs, in the auditorium of the Illinois State Museum
We will have light refreshments after the presentation and there will be show and tell from the members that you can enjoy.
