Analysis of GICy indices derived from Australian magnetometer data shows that only southern Australian regions reached the “moderate” risk levels defined in this study with mainland southern Australia stations reaching this risk level twice over the previous two solar cycles. Southern Australian regions such as Tasmania reached moderate levels approximately 20 times during the previous solar cycle. Furthermore, elevated risk levels are typically only observed in Australia during solar maximum and its decline phase.]]> Wed 11 Apr 2018 11:49:40 AEST ]]> Observations of geomagnetically induced currents in the Australian power network https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:14007 Wed 11 Apr 2018 10:54:18 AEST ]]>
