The above plots show current observations of the Earth's magnetic field strength r
ecorded at Coonabarabran, NSW, Australia.  These are measured in units of nano-Tesla (nT), with the time scale in Greenwich Mean Time (GMT), also known as UTC, and thus 10* hours need to be added to read NSW local time (* 11 hours during daylight saving).  The three coloured lines indicate the three components of the local magnetic field, with blue indicating the north-south component, red the east-west component, and green the vertical component.  Each day at 00:00 hours UTC, the plot sets the current magnetic field strength as zero, and thereafter the variations deviate from this.
