Observed Regional daily pc3 Indices 02 JUL :
Townsville 0 (Quiet)
Learmonth NA
Canberra 55 (Unsettled)
Hobart 38 (Quiet to unsettled)
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.
Estimated AFr/Ap Indices 02 Jul : A
Fredericksburg 7
Planetary 8
Observed AFr/Ap Indices 01 Jul : A K

2B. MAGNETIC FORECAST
Date Ap Conditions
03 Jul 10 Mostly quiet to unsettled.
04 Jul 8 Mostly quiet. Isolated unsettled periods pssible.
05 Jul 8 Mostly quiet.
COMMENT: The solar wind speed has slowed down from 460km/s
to 390km/s (approximately) over the last 24 hours and Bz
remained predominantly northwards. No other significant
activity has been noticed that could affect the geo-magnetic
activity. The geomagnetic activity is expected to remain
mostly at quiet to unsettled level during the next 3 days.
