ISSUED ON 27 MARCH 2014, BY IPS RADIO AND SPACE SERVICES,
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
1. SUMMARY (18 MARCH - 26 MARCH)
K indices are in UT (0-24). For conversion to local time:
AEST = UT + 10 hours; ACST = UT + 9.5 hours; AWST = UT + 8 hours
Date K-INDICES A

Mar, a weak (14nT) impulse was observed
26 Mar 3132 0012 6
*estimated from real time 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 International Center for Space Weather
Science and Education, Japan.
Quiet to unsettled conditions.
2. FORECAST (27 MARCH - 26 APRIL)
No strong recurrent patterns, however mild activity may be experienced on:
9 Apr, 17 Apr.
Best Quiet Periods:
27 Mar to 8 Apr, 10-16 Apr, 18-27 Apr.
3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: NA
Central Australian Regions: NA
Southern Australian Regions:
Disturbed Periods: None.
Best Quiet Periods: 27 Mar to 26 Apr.
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
Geomagnetic activity can frequently be determined by short timescale
solar events that cannot be forecast a week in advance, particularly
at solar maximum.
