ISSUED ON 02 APRIL 2020, BY Space Weather Services,
FROM THE AUSTRALIAN SPACE FORECAST CENTRE

1. SUMMARY (24 MARCH - 01 APRIL)
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

*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 observed over the previous week.
Similar conditions are expected for the next 7 days with possible 
enhanced solar wind speeds due to coronal hole effects 05Apr-06Apr. 

2. FORECAST (02 APRIL - 02 MAY)
Disturbed Periods: No strong recurrent patterns, however mild 
activity may be experienced on: 15 Apr,  17-19 Apr,  26-27 Apr.

Best Quiet Periods: 2-14 Apr,  16 Apr,  20-25 Apr,  28 Apr.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions: Quiet

Central Australian Regions: Quiet

Southern Australian Regions: 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.

PLEASE NOTE:
Geomagnetic activity can frequently be determined by short timescale 
solar events that cannot be forecast a week in advance, particularly
at solar maximum.
