The leading edge from the CME associated with Sunday's X-Class flare duly arrived early on the 6th but was preceded at 1800z on Monday 5th by a storm (Kp=5) from another event that didnt make the headlines. This was a little exceptional as it only took 48 hours to get here where as the normal travel time for a CME is 56 to 72 hours. The result was that the Kp index hit 8 on Tuesday and was over 5 for most of the day. So expect this to affect LF propagation as early as Saturday, and the effects may be fairly long lived. It looks like conditions will stay interesting for a little while. Cheers de Alan G3NYK alan.melia@btinternet.com
