Friends in Radio Land -

Lightning discharges in the D-region, "sprites" as observesd by the
University of Minnesota, could give rise to momentary bursts of Xrays 
and electrons but the ionization would probably be gobbled up by oxygen
molecules, forming negative ions. Those may linger for a while as
electron attachment is faster and more frequent than electron detachment
in that region. But the negative ions are too massive to participate in
any absorption processes so would have little effect on low-band signals.
QRN from the discharges is another matter, however.
