*estimated from real time data

The minor storm periods observed on 21 August 
were due to sustained period of mildly southward
inter-planetary magnetic field. The southward IMF
might have been caused by flare/CME activity 
around that period. Geomagnetic activity reached 
upto active level on 22 August, most likely due 
to the CME activity.  Minor storm periods, observed 
on 26 August, also seem to be a result of the CME 
activities observed in the previous few days.

2. FORECAST (29 AUGUST - 28 SEPTEMBER)
Disturbed Periods: 8-9 Sept., 11-18 Sept., 24 Sept.

Best Quiet Periods: 29 Aug.- 4 Sept., 19-21 Sept.


PEASE 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.
