1AM-LT Spike . A 23-dB@[A1]/20@[A2] peak when it should be otherwise quiet; Then, again, 24 hrs later, similar happened for a longer duration.
Recent series of what appear to be whistler signals; we're going to explore "whistler signals".
! Important note on Tomsk !
As a reminder, the Tomsk SOS reports are coming from a learning institution. Tomsk State University is a public institution, a technical university. As a condition of their public charter, they are required to make public this information. It is simply reasonable to understand that this information is used to illustrate the process, and not to be consulted as a cause to physiological conditions. Amplitude spikes are local. The Horizontal magnetic component is what travels world-wide.
Brief observation:
Relative to "The Schumann" today's lesson is in the di-urnal variation.
There's a difference between the daytime and nighttime readings;
subsequently within the 22 year cycle there's seasonal variations as well.
It takes alot of years of study to truly see the pattern developing over time.
It takes dedicated study of the day-to-day to start.
Honestly, few but me could spend the time doing that much study of these things, lol
..ok, so as I've said elsewhere, the normal routine of the sun is that it's fully "down" at 2300LT (11pm local time),
Sun is "up" around 5 am.
So, between 23LT and 5LT there should be little to nothing last night, or the last night being show.
BUT WAIT!! Around 1LT there's a sizable spike!
That's actually HUGE activity.
During the middle of the night (25th), there was a notable spike. ...gotta check the times on the spikes.
We expect to see spikes during the day, but not the middle of the night.
Middle of the night is the nighttime side of the planet. The ionosphere is actually "leaking" schumann resonances during the night time, because the ionosphere is not getting charged from the IMF link.
Regularly, people assume that the spikes are solar-based.
Not at 1am locally it's not solar based.
We remember Schumann resonances are caused by two things: lightning discharges, and an ionosphere.
If there's a weak ionosphere at that time, there's not a notable ceiling, the resonances leech out into space to be detected by satellite.
So, a 1am LT burst is an excess of atmospheric influence, and not solar burst.
The di-urnal patterns tell a person alot.
It's like a statistical baseline from which to extrapolate data.
Knowing it's usually quiet at that particular time, allows us to make some educated guesses about what's actually happening.
Also, some interesting "curved lines" at the lowest end of the frequencies,,, I'm wondering it it's a tool flaw somehow, OR, if those are "whistler signals"?
