Solar activity was moderate during 17 September due to an M1.1 flare
from solar region 2415 in addition to many C-class flares. Further
C-class flaring is expected from region 2415 with a reasonable chance
of M-class flares. No earth-directed CMEs were observed during 17
September. A coronal hole continues to produce mildly elevated solar
wind speeds which are expected to decline slowly during the next 24-48
hours. Geomagnetic conditions over the Australian region were mostly
quiet to unsettled with elevated activity at high latitudes. Isolated
active and minor storm periods at high latitudes are possible as
coronal effects subside otherwise conditions should be mostly quiet to
unsettled. Mildly degraded HF conditions were observed during 17
September over the Australian region due to low levels of ionising
radiation and sustained mildly elevated geomagnetic activity levels.
Similar HF conditions are expected with the possibility of short-wave
radio fadeouts.
