Solar activity is moderate as far as the emergence of the number of new

Solar activity is very low as far as the number of new solar flares, only 1 
solar flare occurred. The largest solar flare in magnitude in the past 24 
hour period was a very small size B4.7, associated with sunspot group #11670 
which is located at approximately N13W63.

The daily solar flux index (SFI) has been above 100 for 9 consecutive days, 
currently at 104.3.

The daily sunspot number (SSN) has languished below 100 for 24 consecutive 
days, currently (NOAA) at 57.

The geomagnetic field has been quiet for 1 consecutive day with the Kp 
(planetary) index in the 0-2 range. As follows are the Potsdam WDC 3 hour Kp 
(planetary) intervals 12222211.

The Dst ranged between +5 and -20.
