Townsville 0 (Quiet)
Learmonth 0 (Quiet)
Canberra NA
Hobart 70 (Active)
Pc3 pulsations are high frequency (10-45 second period) variations
of the Earths magnetic field. Daily pc3 indices are the daily sum
of 20 minute pc3 indices for that station.
Estimated AFr/Ap Indices 29 Jan : A
Fredericksburg 10
Planetary 12
Observed AFr/Ap Indices 28 Jan : A K
Fredericksburg 9

2B. MAGNETIC FORECAST
Date Ap Conditions
30 Jan 16 Quiet to unsettled with possible active levels.
31 Jan 12 Quiet to unsettled.
01 Feb 8 Quiet
COMMENT: A partial halo CME oberved in association with the C2-flare
on 27 January is expected to impact the Earth during 30 January.
Only slightly elevated geomagnetic activity is expected to follow,
otherwise activity is expected to remain mostly quiet to unsettled
during the next three days.

3A. GLOBAL HF PROPAGATION SUMMARY
Latitude Band
Date Low Middle High
29 Jan Normal Normal Normal-fair
PCA Event : No event.
3B. GLOBAL HF PROPAGATION FORECAST
Latitude Band
Date Low Middle High
30 Jan Normal Normal-Fair Fair
31 Jan Normal Normal Normal-Fair
01 Feb Normal Normal Normal-Fair
COMMENT: HF conditions are expected to remain mostly normal for
the next three days, however minor depressions may be observed
for mid-high latitudes for 30 January as the result of anticipated
slightly elevated geomagnetic activity.
