W4HM DISCUSSION OF DAILY SOLAR SPACE AND GEOMAGNETIC WEATHER-
For Wednesday February 27, 2013

Solar activity is low as far as the emergence of the number of new sunspot 
groups. Currently there are 3 new un-numbered sunspot groups and 4 existing 
numbered sunspot groups.

Solar activity is low as far as the number of solar flares, 2 occurred. The 
largest solar flare in magnitude was a very small in size B8.3, which 
occurred at approximately S18W05 and associated with sunspot group #11682.

The daily solar flux index (SFI) has been at or above 100 for 1 day, 
currently (NOAA) at 103.1.

The daily sunspot number (SSN) has been below 100 for 7 consecutive days, 
currently (NOAA) at 61.

The geomagnetic field has been inactive for 4 consecutive days with the Kp 
(planetary) index in the 0-2 range, which is quiet geomagnetic conditions. 
As collected by Potsdam Germany WDC the 3 hour Kp (planetary) intervals were 
1211001. As collected by NOAA/SWPC the 3 hour Kp (planetary) intervals were 
11111101.

Via Kyoto U. the Dst ranged between +12 and -4.

Via SOHO and sollen.info the maximum and minimum solar wind values were 
291-336.

Via NOAA the maximum background x-ray solar flux value was B2.0.

Via NOAA the energetic proton flux has fallen below (10+0).
