1. SUMMARY (23 APRIL - 01 MAY)
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

 30 Apr   2211 2333    9  In the BOM magnetometer data for 30 
                          Apr, a weak (10nT) impulse was observed 
                          at 1225UT.

*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.

G0 conditions observed all week. A mild increase in geomagnetic
activity was observed on 26-Apr. No significant geomagnetic activity
followed the weak impulse on 30-Apr.

2. FORECAST (02 MAY - 01 JUNE)
Disturbed Periods: 
16 May.

Best Quiet Periods: 
 7-12 May,  14-May,  19-22 May,  25-26 May.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: NA

Central Australian Regions: NA

Southern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 2-25 May.


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.
