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

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 02 Jul: 114/65


1B. SOLAR FORECAST
             03 Jul             04 Jul             05 Jul
Activity     Low                Low                Low
Fadeouts     Possible           Possible           Possible
10.7cm/SSN   115/66             115/66             110/60

COMMENT: Solar activity stayed at low levels today. The largest 
flare was a C7.1 at 1749 UT from region 1785(S11E62). Solar wind 
speed showed a gradual decrease from around 450 to 400 km/s during 
the UT day today and the Bz component of IMF varied between +/-3 
nT most of the times during this period. The CME of 30 June may 
be weakly geoeffective on 4 July. Solar activity is expected 
to stay at low levels for the next three days with some possibility 
of isolated M-class activity.

Observed Regional daily pc3 Indices 02 Jul : 
      Darwin               6   (Quiet)
      Townsville           0   (Quiet)

      Gingin               2   (Quiet)
      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.

COMMENT: Quiet levels of geomagnetic activity were observed today. 
Nearly similar levels of geomagnetic activity may be expected 
on 3 July with possibility of rise to unsettled levels on 4 and 
5 July with some possibility of active levels on 5 July.

COMMENT: Minor to mild MUF depressions observed on several locations 
during the last 24 hours. Mostly normal HF conditions may be 
expected on 3 July. Minor to mild MUF depressions and degradations 
in HF condition are possible on 4 and 5 July, especially on high 
and some mid latitude locations due to expected rise in geomagnetic 
activity on these days.

during the last 24 hours. Mostly normal HF conditions may be 
expected on 3 July with the possibility of minor to mild MUF 
depressions and degradations in HF condition on 4 and 5 July 
due to expected rise in geomagnetic activity on these days.
