SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT

FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 15 JUNE AND FORECAST FOR 16 JUNE - 18 JUNE
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 15 Jun:  Low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 15 Jun:  76/14


1B. SOLAR FORECAST
             16 Jun             17 Jun             18 Jun
Activity     Very low           Very low           Very low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN    75/13              75/13              80/20
COMMENT: Expect solar activity to be very low for the next three 
days. Region 10892 unexpectantly produced two C-class flares 
yesterday. This region has decayed as it rotated across the solar 
disk and is not expected to continue producing more C-class flares 
as it rotates around the west limb. SOHO ACE shows the solar 
wind steadily increasing to 600 km/s due to a small coronal hole 
moving into a geoeffective position. Expect the solar wind to 
steadily decrease as the coronal hole moves westward. The interplanetary 
magnetic field has fluctuated between -/+ 10 nT thoughout yesterday 
and it appears to be settling back to neutral.

Observed Regional daily pc3 Indices 15 Jun : 
      Canberra            46   (Unsettled)
      Learmonth            2   (Quiet)
      Culgoora            43   (Unsettled)
      Hobart              51   (Unsettled)
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.

16 Jun     8    Quiet to Unsettled 
17 Jun     8    Quiet to Unsettled 
18 Jun     8    Quiet to Unsettled 
COMMENT: Geomagnetic activity was quiet increasing to active 
due to coronal hole effects yesterday. Expect the geomagnetic 
activity to decrease to unsettled to quiet over the next three 
days as coronal hole moves westward. 
A weak (20nT) impulse was observed in the IPS magnetometer data 
at 1414UT on 15 Jun.

3A. GLOBAL HF PROPAGATION SUMMARY
	            Latitude Band
Date        Low            Middle         High 
15 Jun      Normal         Normal         Normal-poor    
PCA Event : No event.

3B. GLOBAL HF PROPAGATION FORECAST
	            Latitude Band
Date        Low            Middle         High 
16 Jun      Normal         Normal         Normal-Fair
17 Jun      Normal         Normal         Normal-Fair
18 Jun      Normal         Normal         Normal-Fair
COMMENT: HF conditions were mostly normal at low and mid latitudes 
yesterday with isolated cases of sporadic E at low latitudes. 
High latitude ranged from normal to periods of poor conditions 
with cases of sporadic E and spread F due to geomagnetic activty. 
Expect conditions to improve over the next three days.
