FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 15 JUNE AND FORECAST FOR 16 JUNE - 18 JUNE
STATUS INDICATORS SOL:** YELLOW ** MAG:GREEN ION: ** YELLOW **
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 15 Jun: High
Flares Max Fadeout Freq. Sectors
M6/1N 1013UT probable lower European
Observed 10.7 cm flux/Equivalent Sunspot Number for 15 Jun: 197/149
GOES satellite data for 14 Jun
Daily Proton Fluence >1 MeV: 6.4E+05
Daily Proton Fluence >10 MeV: 1.7E+04

Fluence (flux accumulation over 24hrs)/ cm2-ster-day.
1B. SOLAR FORECAST
16 Jun 17 Jun 18 Jun
Activity Moderate Moderate Moderate
Fadeouts Possible Possible Possible
10.7cm/SSN 200/152 200/152 195/147
COMMENT: Flares and shortwave fadeouts expected due to active
solar region.
ACE EPAM data indicates an energetic ion enhancement event beginning
15/0805UT, which can be a precursor to increased geomagnetic
activity over next 24 hours.

2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 15 Jun: Quiet
Estimated Indices 15 Jun : A K
Australian Region 4 2222 0012
Darwin 5 2322 0013
Townsville 2 1210 0010
Learmonth 8 3222 -223
Canberra 5 2322 0001
Hobart 3 1222 1001
Observed Regional daily pc3 Indices 15 JUN :
Darwin 4 (Quiet)
Townsville 64 (Active)
Learmonth 0 (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 15 Jun : A
Fredericksburg 10
Planetary 12
Observed AFr/Ap Indices 14 Jun : A K
Fredericksburg 6
Planetary 9 2112 2334
2B. MAGNETIC FORECAST
Date Ap Conditions
16 Jun 9 Quiet to Unsettled
17 Jun 9 Quiet to Unsettled
18 Jun 14 Unsettled to Active
COMMENT: Mild activity, with isolated active periods may be experienced
during the forecast period.

3A. GLOBAL HF PROPAGATION SUMMARY
Latitude Band
Date Low Middle High
15 Jun Normal Normal Poor(PCA)
PCA Event : 10Mev Proton/PCA Event Began 15 06 2001 1835UT and is in progress
3B. GLOBAL HF PROPAGATION FORECAST
Latitude Band
Date Low Middle High
16 Jun Normal Normal Poor(PCA)
17 Jun Normal Normal Poor(PCA)
18 Jun Normal Normal Poor(PCA)
COMMENT: Mildly degraded HF conditions expected at high latitudes
only during local night hours High latitude communications are
currently degraded by increased absorption associated with a
proton (PCA) event
