Hi Jay, Alan,
Well, at least your timing is very accurate since both emails from you
arrived to the same time, well done! :-)

Hi Stefan, the Dst index is a measure of the quanity of charge
circulating in the Equatorial Ring Current .....the Van Allen Belt.
This "peaked" only at mid-day today (Kp=6) when the shocks from
previous events arrived. It till not be until perhaps tonight or more
likely tomorrow night, that the full effect of these eleectrons
"precipitating" into the ionosphere, and diffusing to the D-region at
mid-latitudes, that the absorbtion of signals at LF will be seen.
There is even some belief that signals are enhanced just before they
dive........I have seen no firm evidence of this.....so it may be
wishful thinking :-))

Hi Jay,
Thanks for monitoring and the report.
Didn't you say there is no chance when DST levels are below - 20 nT? Why
was the SNR so good this time?

Stefan & T/A enthusiasts
20 dB+ s/n in 28 mHz last night despite Tstorms off the east coast.
DST was already on the downslide during the reception period but
seemed to have little effect on your signal ... ending up at about
-40 nT at the 0600Z fadeout. Currently DST at -110 nT ... ;~(

LF,
This night i'm on 136.172 kHz again, running good old DFCW-90 to the
world until about 6 UTC.
