CCRM Propagation Bulletin #317
OBSERVATION PERIOD : 2014 01 08 0947 UTC
INTERFERENCE RISK : Abnormal Solar Activity : High velocity proton flux >100MeV and strong Radio Burst

From NOAA : (today 09:23 UTC)
	the proton event continues. 
	The proton flux is still rising for the > 10MeV and >50MeV protons and is starting to decline for >100MeV protons. 
	The current value for >10MeV protons is around 700 sfu.


Observations at the CCRM

	Minor effect on the pan-European aero HF radio-communications.  
	No Effect detected on the VUHF band.


Observations from NOAA

	Minor effect on the HF radio-communication,
	but very strong attenuation on the HF radio-communications at the polar region.
