Re: LF: Over the Pole and far far away

Hi Stefan yes its obious from my Dst analysis that this only points to one cause of attenuation. My guess is "leakage" for your path which is probably not polar.

Hi Alan,

The DST stuff may not look that bad but i didn't get a single WSPR-15 decode on LF by UA0SNV, so there must be something wrong! ;-)

Hi Laurence yes its possible the proton didnt seem to be up on NOAA and at this time of year there is still a reasonable amount of daylight so I dont really know I havent found any other mechanism that account for that amount of change. The Dst isnt brilliant but its not that bad and bouncing around a bit so there is nothing there to suggest big absorption. The only thing is the surprisingly quiet nature oof Solar actiity for this time in the cycle. How long has it been depressedthat badly with you??

Thanks Alan - yep could be leakage but this morning I see the low/high Proton levels  were way up just for a short while and now back down to flat line too - though I see whe are going to get a little Coronal for a while.
 
This isnt just on LF MF but even HF is a little depressed -  so maybe a little kick of the present mid lat K3 will help.  Odd stuff this... DCF39 is something like >50dBr or more down on where it was this time last year (on a good day)
 
Even the Path to Texas wasnt good last night at MF. Cheers from a snowy hilled Alaska

Hi Laurence, thaksor your observations. It does not seem to absorpyion by precipitated electrons. However the solar X-ray flux has been very quiet for some time now(which is a bit odd)  I wonder if we are suffering ionospheric leakage at least on your path. That is where not all th signal is refracted but a considerble portion goes right through the E layer out into space??

 

If that is the case what we might need is a minor geeomag storm to beef up the electron density again.
