2003 ... the X-45 Solar Flare … after that, there were articles, (now I can't find them but they were up because I posted their link in several places at the time), speaking of the fact we had lost 75% of our thermosphere (the thickest part of our atmosphere).  They changed the scale by which they measure solar flares after that event.  Anything in the X class today would have been above an X-10 to X-20 before the change … an extreme rare event but common to have X flares today.  The Sun is sick.  You don't expect them to broadcast that fact do you??  The Sun is now putting out energies that are not to our benefit, and/or our thermosphere is still depleting and that may be the real reason for the 'chem trails' … may be helping keep down on the skin cancer too.  IF these frequencies are solar origin … I would suggest the Sun is getting sicker and not better.
