FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 08 JUNE AND FORECAST FOR 09 JUNE - 11 JUNE

COMMENT: Solar activity has been low with a single C1 flare from 
region 1762(S28W87). This region, which has produced M class 
flares in recent days, will rotate off the visible Sun over the 
next day. Region 1765(N08W22) has grown in magnitude and complexity 
and may produce C class flares, with a possibility of M Class, 
over the next few days. The solar wind conditions returned to 
normal over the last 24 hours. A CME was observed in LASCO and 
STEREO coronagraphs produced from an M5 flare that occurred at 
2250UT on the 7th of June. The material is directed mainly to 
the south and is unlikely to be geo-effective.

Observed Regional daily pc3 Indices 08 Jun : 
      Darwin               8   (Quiet)
      Townsville           0   (Quiet)

      Gingin              NA
      Canberra             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 and have been shown to be
well correlated with rejection of high resolution aeromagnetic
survey flight-line data. 

NOTE: Indices may have been generated from data obtained in 
cooperation with the following organisations: Geoscience Australia, 
University of Newcastle Space Physics Group, Australian Government 
Antarctic Division and International Center for Space Weather 
Science and Education, Japan.

09 Jun    20    Unsettled to Active
10 Jun    12    Unsettled
11 Jun    10    Quiet to Unsettled

COMMENT: IPS Geomagnetic Warning 12 was issued on 7 June and 
is current for 7-9 Jun. A glancing blow from a CME is anticipated 
to arrive sometime in the first half of the UT day on the 9th 
of June. This may cause Active conditions on arrival followed 
by Unsettled. A weak coronal hole high speed stream is expected 
to take effect from the 10th, maintaining Unsettled conditions 
for the remainder of the forecast period.

Observed Australian Regional MUFs
   Cocos Island Region:
      Enhanced by 30% during local day.
      Near predicted monthly values during local night.
   Niue Island Region:
      Near predicted monthly values during local day.
      Depressed by 25% during local night.
   Northern Australian Region:
      Near predicted monthly values during local day.
      Depressed by 15% during local night.
   Southern Australian and New Zealand Region:
      Near predicted monthly values.
   Antarctic Region (Casey/Scott Base/Davis/Mawson):
      Near predicted monthly values over the UT day.

Predicted Monthly T index for June:  67

4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date   T index  MUFs
09 Jun    65    Near predicted monthly values
10 Jun    60    Near predicted monthly values
11 Jun    60    Near predicted monthly values

COMMENT: Mostly normal HF conditions are expected for the next 
few days. Some depressed periods are possible in southern and 
polar regions due to mild geomagnetic activity and low levels 
of ionising UV flux.
