Measuring Magnetic Fields Produced By Lightning With A Search Coil Magnetometer
	Derek M. Dolney and Christopher Onken

We are working in collaboration with the Lightning Bolt group in the Department of Physics and Astronomy at the University of Minnesota.

The goal of this project is to construct a search coil magnetometer which we will use to measure the magnetic fields produced by lightning. The magnetometer will be used to measure magnetic fields from the ground during a lightning storm.

Our coil is now complete. Feel free to view our frequency response curves.

We made a trip to the O'Brien observatory on 5/15/99. We did not get any lightning, but we made some measurements of noise and interference, and tested different amplifiers, filter schemes, and coils. Here are some of our results.
