*estimated from real time data

This period  started with  enhanced  geomagnetic activity 
upto  major storm level on  day one due to a CME. From 19 
to 21 February a favourably  placed coronal hole kept the 
activity  mostly from unsettled to active  level.  In the 
last two days of the period, coronal hole activity raised 
the  geo-magnetic activity  upto active levels. This rise 
in geo-magnetic activity  is expected to continue for the 
next two days. 

2. FORECAST (27 FEBRUARY - 29 MARCH)
Disturbed Periods: 27,28 February, 6 March, 13-21 March, 
		   25-27 March.

Best Quiet Periods: 4,10,12 March, 23-24 March. 


PLEASE NOTE:  
At this time of the solar cycle, space weather conditions 
are frequently determined by short timescale events, not 
able to be forecasted a week in advance.
