It was showing all the right indications here and was instantly recognisable on a waterfall display. As I said in my earlier message I think the exceptional strength for a short period may have been a propagation effect connected with an X-ray flare around the middle of the day yesterday. Conditions did seem to be returning to what we have come to regard as 'normal', i.e. we dont hear it (if on) in daytime. However yesterday's plot from Brain CT1DRP shows that daytime levels of DCF39 where enhanced by over 10dB at times, and the night-time levels were similarly depressed. This is possibly connected with the Kp=4 conditions we have seen recently and the storm that lifted the index to 5 on the morning of the 2nd Feb ( note the 3 day gap again). There are posibilities CFH will pop up again as there is a 'possibility' (NOAA terminology) of more minor flares (M-Class) from a current active area on the sun.
