When there was an absence of hard evidence at the tunguska site there seemed a need to take a
different approach and assemble any evidence that may have something in common
to that timeframe.
That may have become unnecessary with the latest addition but the timing is still to me a curiosity.
This has been the objective in this extension of the hyper-sensitive solar system, a look at The tunguska even as it relates to orbital relationship between celestial bodies. To this was added the idea that substorms, in the tail of our planet, bring about events in close proximity to the planet.
The intense Auroras that preceeded the Tunguska event and modern observation of this same activity, if in fact aurora can be connected to substorms, may be pieces to add to the puzzle. But there is more to consider from the ground up to and beyond the ionosphere in the form of the lumeneous events that mark activity from above. We can also look at how big storms come and go to get clues about what is involved. An important detail about the Tunguska event is the time of day in which it happened, early am, the tail-side of the planet.
Over time and through further consideration of the magnitude of electircal charge stored in and around planets we should find more clues that were overlooked because of scientific tunnel vision. In the presence of evidence from my experiments with electrical discharge i have seen high energy discharges where i never thought possible, all i had to do was add vertical relief to the CRT experiments with the outcome being not a bit short of amazing in more ways than one. If planetary bodies and their enviornment are in any way like a capacitor, a leaky capacitor from Wal Thornhill's perspective, then an energized CRT is quite indicative to planetary scarring processes. The addition of vertical relief took an otherwise tame electrostatic environment, where low level discharges were the norm, and gave it painfully intense potential from those raised surfaces. At larger scale, moons and above, there are certainly conditions beyond the scope of the CRT experiment but extremely tall planetary features may be more than geologic formation.
