[NZ4O Spaceweather] Moderate Geomagnetic Storming

[Thomas F. Giella NZ4O]

On Friday February 5, 2011 recurrent trans-equatorial coronal hole 
#436(#433) was in geo-effective (Earth facing) position and impacted Earth's 
magnetic field in a negative manner, producing a Kp of 6 (moderate 
geomagnetic storming conditions).

The end result was a reduction in the F2 layer maximum usable frequency 
(MUF...) that negatively effected propagation conditions on 10, 12 and 15 
meters.
