SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT

FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 02 JUNE AND FORECAST FOR 03 JUNE - 05 JUNE
STATUS INDICATORS SOL:GREEN   MAG:*YELLOW*   ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 02 Jun:  Low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 02 Jun: 129/82


1B. SOLAR FORECAST
             03 Jun             04 Jun             05 Jun
Activity     Low                Low                Low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN   130/84             130/84             130/84

COMMENT: A CME associated with the C3-flare observed late in 
the UT day of 1 June is not expected to be geoeffective. All 
visible solar regions are relatively simple. Solar wind parameters 
suggest the Earth was under the influence of a solar sector boundary 
crossing during 2 June. The IMF NS component was weakly negative 
during the most of the latter half of the UT day.

      Mawson              17   11111346

Observed Regional daily pc3 Indices 02 Jun : 
      Darwin               2   (Quiet)
      Townsville           0   (Quiet)
      Learmonth            0   (Quiet)
      Alice Springs        0   (Quiet)
      Gnangara             4   (Quiet)
      Canberra             0   (Quiet)
      Hobart               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 Space Environment Research Center, Japan.

2B. MAGNETIC FORECAST 
Date      Ap    Conditions
03 Jun    10    Quiet to Unsettled with isolated Active periods
04 Jun    15    Unsettled to Active
05 Jun    12    Unsettled

COMMENT: Unsettled and isolated Active periods are expected at 
times over the next couple of days as the Earth comes under the 
influence of an anticipated coronal hole solar wind stream. Storm 
levels may be observed at high latitudes.
