Cocos Island and 131 for Darwin (both enhanced). However, the
T index for Niue was only 22 (depressed). T indices for the mid-latitude
stations were mostly in the range of about 50 to 73 (mildly depressed).
Minor geomagnetic storms are expected during 02-04 Oct. This
may lead to depressed conditions for HF radio wave propagation.
