For Tuesday February 06, 2013

Solar activity is low as far as the emergence of the number of new sunspot 
groups. Currently there are 3 numbered and 2 new un-numbered sunspot groups.

Solar activity is low as far as the number of new solar flares, 3 solar 
flares occurred. The largest solar flare in magnitude in the past 24 hour 
period was a medium size C1.3, associated with a filament eruption instead 
of a particular sunspot group.

The daily solar flux index (SFI) has been above 100 for 7 consecutive days, 
currently at 104.7.

The daily sunspot number (SSN) has languished below 100 for 22 consecutive 
days, currently at 39.

The geomagnetic field had been quiet for 4 consecutive days with the Kp 
(planetary) index in the 0-2 range. Following are the 24 hour 3 hour Kp 
(planetary) intervals 10000011.

The Dst ranged between +9 and -6.
