OP - You may have found something significant, and here I offer a different hypothesis as to what it might mean.
As I'm sure you are well aware, there is a project at Princeton called the Global Consciousness Project.
Long story short, they are detecting the presence of what can only be described as a global awareness of significant human events being communicated
in the form of synchronicity of random number generators scattered around the world BEFORE said events occur.
Why do I mention this?
Well, perhaps the sun is part of that "global consciousness", and that what you discovered is, in a way, an abstract reflection of the collective
human conscience coming in the form of a sort of Rorschach test. So maybe it is not the
cause of the event, rather it's a reflection of human awareness/emotional response to the event.
