Interestting Andy! there was a slight geomagnetic disturbance round 0600z
this morning (Sat) which pushe dthe Dst down to -25nT I would normally not
expect this to be noticable on LF propagation, but maybe conditions have
been so good for a few days that it is. The Dst has risen sharply during
the day and is now back at -10nT which what it was under good conditions.
Conditions may worsten tomorrow night as the disturbance is due to a coronal
hole flow and it will continue through tomorrow.
It may just skim the icing off the top....I dont tink you will see a major
collapse of propagation conditions.

LF, and all:
I have been seeing the TA conditions slowly begining to drop here in the
35th North parallel.
While those farther to my North still seem to be getting fair to good
propagation.
My best night was on Wed. - the 7th ,when Stefans signal was showing up thru
the entire night.
and on Thursday the 8th, there was a window of about 2 hours between 0100 to
0300 UTC ( the 9th )
but here was between 8 to 10 pm local time. In that window; Stefans signal
peaked the strongest
I have saw it yet, and the TF3HZ grabber showed the same increase.
Strangely; at my QTH;
following that rise in propagation level; it is almost as if someone "
Turned off the switch ".
>From that point till now, reception of Stefans signal has been very spotty
at best.
During the peak times; I was seeing faint traces of " CPM ", and a couple of
times caught Mal in there.
It was fun while it lasted, and hoping it will happen again soon, I would
like to give verifiable signal
receptions from Friendsville, Tennessee, USA..
I will be looking again tonite, but possibly disappointed.. still 2 hours
before dark at this time..
I will switch my grabber to the EU - TA window around 2200 UTC : 73 to all,
and good DX
