"K9 only" and low power record on 160m

I am always amazed by the diversity of the propagation on 160m and sometimes concentration in a small area.
This morning at sunrise, it was "K9 only" for a short opening of 18 minutes with at the end my 20th NA stations of my season (K9YWO):
2014-12-08 07:32 K9AN 1.838170 -24 0 EN50wc 2 F59706 JN07th 6849 50
2014-12-08 07:20 K9PAW 1.838190 -28 0 EN61ar 1 F59706 JN07th 6723 51
2014-12-08 07:14 K9YWO 1.838181 -26 0 EN61fn 1 F59706 JN07th 6708 51

Also to note, the new record "low power across the pond" in the way NA-> EU (Previous W1FVB/F59706 0.5w) maded in the night by our friends Frits and Tom, congratulations to you both:
2014-12-08 02:44 W1FVB 1.838014 -27 0 FN44ej 0.2 G8HUH IO81mg 4992 56

In the way EU-> NA record (also 0.2W) was matched (1st time G4FKK/WU2M) by Chrigel and Rocco:
2014-12-08 06:06 HB9CAU 1.838027 -25 0 JN47 0.2 WU2M FN23tb 6216 299

Thanks to all and GL for the next time...
