*estimated from real time data

The week started with geomagnetic activity at unsettled 
to active levels due to a coronal hole effect. This activity 
declined to quiet levels by the middle of the week and 
remained mostly at quiet level until 10 February. Due to 
the effect of another coronal hole, the geomagnetic activity 
again increased to quite to minor storm periods on 11 February. 

2. FORECAST (12 FEBRUARY - 13 MARCH)
Disturbed Periods: 12 to 14 Feb, 19 to 20 Feb, 23 Feb to 01 March, 
03 to 04 March, 09 to 13 March

Best Quiet Periods: 05 to 08 March


PLEASE NOTE:  
At this time of the solar cycle, space weather conditions

able to be forecasted a week in advance.
