Fluxgate Magnetometer
The NanoTesla LNV-01 Triaxial Fluxgate Magnetometer is a highly sensitive scientific instrument that continuously records the direction and intensity of Earth's magnetic field at the Jenny Jump site. Operating around the clock since June 2008, it samples data every two seconds, 24 hours a day.
The sensor is positioned at the base of a cliff on the property, which helps shield it from electromagnetic interference originating in the surrounding area. This placement is important because the instrument is sensitive enough to detect subtle variations in the geomagnetic field caused by space weather, which includes changes in the electromagnetic and particulate output of the Sun. Solar activity such as coronal mass ejections and solar wind fluctuations can create measurable disturbances in Earth's magnetosphere, and those disturbances show up in our data here at Jenny Jump.
The instrumentation is protected by a Plexiglas enclosure, and the cable connecting the data logger to the magnetometer sensor head is buried underground to further protect it from the elements. Informational posters explaining the project and what the data represents are on display at the UACNJ site.
