Using data from the six Australian continental magnetic observatories, a contour display of the rate-of-change of magnetic total intensity, F, over the continent is shown below. This provides a broad view of how F changes across Australia. The units shown on the contours are in nanoTesla per hour. The grey squares indicate the locations of the magnetic observatories. Both real-time and historic data can be displayed in this format. All maps are generated from a period of 15 minutes of observatory data and available at 15 minute intervals.
