*estimated from real time data

The geomagnetic activity remained mostly at quiet to 
unsettled levels during this period. However, the 
geomagnetic activity rose to quiet to active levels on 
28 December and 31 December. The origin of rise in 
geomagnetic activity on 28 December could not be 
determined. The rise in geomagnetic activity on 31 
December has been attributed to the strenthening of 
solar wind stream due to a coronal hole effect.
