SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 2330UT/22 AUGUST 2012 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 22 AUGUST AND FORECAST FOR 23 AUGUST - 25 AUGUST
STATUS INDICATORS SOL:GREEN MAG:GREEN ION: ** YELLOW **
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 22 Aug: Very low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 22 Aug: 95/41
1B. SOLAR FORECAST
23 Aug 24 Aug 25 Aug
Activity Very Low to Low Very Low to Low Very Low to Low
Fadeouts None expected None expected None expected
10.7cm/SSN 95/41 100/48 100/48
COMMENT: Solar activity was very low over the last 24 hours.
Only some low B-class flares were observed. Solar wind speed
showed a gradual increase from 360 to 440 km/s today. The Bz
component of IMF varied between +/-4 nT for most parts of the
UT day today. A CME was observed in LASCO C3 imagery at 1118UT/22
August. This CME does not seem to be geo-effective. A full halo
CME, that was observed in LASCO C2 imagery at 2024UT/21 August,
is a back side event and is not going to be geoeffective. Solar
activity is expected to be very low to low over the next 3 days.

Estimated Antarctic Regional K Indices 22 Aug :
Macquarie Island 3 11113100
Casey 8 33321111

Observed Regional daily pc3 Indices 22 Aug :
Darwin 0 (Quiet)
Townsville 0 (Quiet)
Learmonth 0 (Quiet)
Alice Springs 0 (Quiet)
Gnangara 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 Space Environment Research Center, Japan.
Estimated AFr/Ap Indices 22 Aug : A
