On Thursday, February 18 at 7:00 p.m., the Leach Library
will host Dr. Alexa Halford for an evening presentation of “Painting the Sky: The
Northern Lights”.
Dr. Halford is a space physics researcher at Dartmouth
University working with the BARREL mission, a multiple-balloon investigation
that will study Earth’s radiation belts. She studied geomagnetic storms and sub-storms
for her Master’s degree at the University of Colorado Boulder, and received her
Ph.D. at University of Newcastle NSW in Australia, where she wrote her thesis
on electromagnetic ion cyclotron waves.
In this slide show presentation, Dr. Halford will discuss
the lore of the aurora, how it has been scientifically studied, and what we are
still learning about these mysterious lights. Also, included in this presentation are recent
images of the Northern Lights taken by Dr. Halford herself.
This presentation is free and open to the public with
seating limited to the first 90 individuals. It will be held in the library’s
lower-level meeting room. Light
refreshments will be served.
