The Time History of Events and Macroscale Interactions during Substorms (THEMIS) Mission Education and
Public Outreach (E/PO) program has placed 12 magnetometers in schools in 10 Northern states. This program
is called the Geomagnetic Event Observation Network by Students (GEONS). As part of the GEONS program
teachers were tasked with developing activities around the mission science and data from the ground-based
research-quality magnetometers located at their schools. An activity by Petersburg, AK teacher Vic Trautman that
has students determine daily average local magnetic field intensity was adapted for this project. Students would
use Image J, a Java based public domain image processing software rather than making measurements of
THEMIS magnetometer data plots by hand. The local magnetic field intensity data can then by examined by
students to seek out patterns. Research can then be done to attempt to explain these patterns.
This past summer research was done to determine what patterns might arise and how the students might be
able to explain these results. Data on variations over time in the average daily solar proton (H+) density, velocity
and IMF orientation of the solar wind were obtained from the Advanced Composition Explorer (ACE) spacecraft.
These were plotted against daily average B (local magnetic field intensity) values calculated from data gathered
from THEMIS E/PO ground station magnetometers located at 3 different locations - Carson
City, Nevada; Loysburg, PA; and Remus, MI. Data were taken for periods of quiet geomagnetic. While no
significant correlation was found between solar wind momentum and local B values in data having either a
southward directed or a northward directed IMF, a seasonal oscillation in local magnetic field intensity was
discovered in the data. A literature search confirmed that interaction between the tilt of
Earth's dipole and IMF causes seasonal variations in local magnetic field intensity. Results
showed the most obvious oscillation pattern in local B values at the lowest latitude - the
Carson City, NV, site.
Several classroom activities were designed around the completed research project. These activities will be used
at Chippewa Hills High School to lay the foundation for a group of students to engage in an independent research
project to be entered in the West Michigan Regional Science and Engineering Fair. A student project on changes
in active region magnetic field activity as the result of X-class flaring was done last year as a result of teacher
involvement in NOAO's Teacher Leaders in Research Based Science Education (TLRBSE)
program, and student involvement in NOAO's Teacher Observing Program (TOP).
