SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 10/2330Z JUNE 2006 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 10 JUNE AND FORECAST FOR 11 JUNE - 13 JUNE
STATUS INDICATORS SOL:GREEN MAG:GREEN ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 10 Jun: Very low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 10 Jun: 76/14
1B. SOLAR FORECAST
11 Jun 12 Jun 13 Jun
Activity Very low Very low Very low
Fadeouts None expected None expected None expected
10.7cm/SSN 75/13 75/13 75/13
COMMENT: Solar activity remained very low today. Region
892(S07W14) produced a B5.9 flare at 1639UT. The solar
wind speed gradually decreased from 630 to 500 km/s
during the UT day today, thus signalling a declining
coronal hole effect. The north-south component of the
interplanetary magnetic field (Bz) showed minor
fluctuations on both sides of the normal value throughout
the UTday. Solar activity is expected to remain at very
low levels for the next three days.
