Hi Jacek, interesting but there is no real cause for absorption at pre=
sent,
and it would not affect groundwave. However there was a flare this mor=
ning
at around 0400 0500z . This would have enhaced the skywave ay 225kHz=
  and
perhaps lead to destructive interference with the groundwave??

there seems to be increased absorption right now, maybe due to solar
x-rays. i've just tried to show my daughter how a crystal radio works,=
 and
can barely receive Warsaw 1 on 225kHz (with active antenna and tuned
circut). normally i would receive several stations with just a diode=
 and
low-impedance headphones.
