*estimated from real time data

The period started with geomagnetic activity mostly
at quiet levels for the first five days. The activity 
rose to severe storm levels during the last four days 
of the period due to the arrival of CMEs during this 
period.  The geomagnetic activity is expected to 
remain enhanced to storm levels during the next two 
days due to the effect of more CMEs.

Disturbed Periods: 11, 12, 16 November, 04 to 09 December. 

Best Quiet Periods: 14, 15 November, 17 November to 03 December,
