FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 26 JANUARY AND FORECAST FOR 27 JANUARY - 29 JANUARY
STATUS INDICATORS SOL:GREEN MAG:GREEN ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 26 Jan: Very low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 26 Jan: 80/20
1B. SOLAR FORECAST
27 Jan 28 Jan 29 Jan
Activity Very low Very low Very low
Fadeouts None expected None expected None expected
10.7cm/SSN 80/20 78/17 78/17
COMMENT: The solar wind speed remained mostly below 390 km/s
over the past 24 hours; the interplanetary magnetic field Bz
component ranged between +/-4 nT. Region 1042 produced a number
of B-class x-ray events over the past 24 hours. C-class x-ray
events are still possible from regions 1041 and 1042.

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.
