FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 25 MARCH AND FORECAST FOR 26 MARCH - 28 MARCH
STATUS INDICATORS SOL:GREEN MAG:GREEN ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 25 Mar: Very low
Flares: None
Observed 10.7 cm flux/Equivalent Sunspot Number for 25 Mar: 88/32
1B. SOLAR FORECAST
26 Mar 27 Mar 28 Mar
Activity Low Very low Very low
Fadeouts None expected None expected None expected
10.7cm/SSN 88/32 89/33 89/33
COMMENT: Region 1057 (N15E45) has continued to increase in size
and produced a number of sub-flares. New region 1058 (N27W06)
was numbered today. A slow-moving CME was observed from the LASCO
and STEREO B imagery ejecting from the far side around 0242 UT.
This may have been associated with the type II and III radio
events around 0128 UT. Solar wind parameters became disturbed
in the second half of the period with wind speed increasing to
about 440 km/s and the IMF Bz ranging between about +/-10 nT.
Solar wind parameters should remain disturbed today. A coronal
hole is currently located at central meridian.

Geomagnetic field for Australian Region 25 Mar: Quiet to unsettled
Estimated Indices 25 Mar : A K
Australian Region 8 22122331
Darwin 7 21122331
Townsville 7 11122332
Learmonth 7 21122331
Canberra 3 12011220
Hobart 5 11122221
Casey(Ant) 7 23221221
Observed Regional daily pc3 Indices 25 Mar :
Darwin 2 (Quiet)
Townsville 0 (Quiet)
Learmonth 0 (Quiet)
Alice_Springs 0 (Quiet)
Gnangara 4 (Quiet)
Canberra 7 (Quiet)
Hobart 2 (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.
