Over the last few days, the signals went from SD ruling the sky to SB and the Angels doing the same, and then back to SD. Then the songs went away. Only a virtual chaos seems to remain as of this evening. Which all seems a bit contrary to what should have happened according to my model given typical air masses. So maybe something odd is afoot? Maybe, anyhow.
