The geomagnetic activity remained mostly at quiet 
levels from 01 to 06 February with some unsettled 
periods observed on 02 and 06 February, and some 
active periods on 03 February. The activity rose 
from quiet levels to minor storm levels on 07 February 
when the earth entered the high speed coronal hole 
wind stream. The effect of this coronal hole has been 
showing a gradual decline since 08 February as the 
geomagnetic activity remained at Quiet to Active 
levels on 08 February and at Unsettled to Active 
levels on 09 February.
