Hobart 14 (Quiet)
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 28 Nov : A
Fredericksburg 8
Planetary 12
Observed AFr/Ap Indices 27 Nov : A K

2B. MAGNETIC FORECAST
Date Ap Conditions
29 Nov 10 Quiet to Unsettled
30 Nov 10 Quiet to Unsettled
01 Dec 13 Unsettled to Active
COMMENT: Activity is likely to increase late on 1 Dec due to
recurrent coronal hole activity.

3A. GLOBAL HF PROPAGATION SUMMARY
Latitude Band
Date Low Middle High
28 Nov Normal Normal Normal
PCA Event : No event.
3B. GLOBAL HF PROPAGATION FORECAST
Latitude Band
Date Low Middle High
29 Nov Normal Normal Normal-Fair
30 Nov Normal Normal Normal-Fair
01 Dec Normal Normal Normal-Fair
COMMENT: Sporadic E may disrupt F region communications at times;
mostly during the day and evening. Lower frequencies may be required
later on 1 Dec due to an increase in geomagnetic activity.
