This started as a lark, and, frankly, I expected to have an easier time getting down to well below 0.05% stability. Ha, that wasn't the case. I'm maintaining just about that stability over a day, so I should be able to see the larger events without much trouble. Anyway, I'm really looking for more smoke from the end of the gun before I go to much more trouble. This experiment doesn't even have a reasonable theory behind it, as you mentioned. If I become more convinced that this actually works, I'll set up a more sophisticated experiment with automatic logging and a better chamber or two. Right now it feels a little like reception of "scalar" waves or other similar nonsense, and I don't think it warrants much more attention just yet. I don't want to end up on late-night radio! : )
As I type, I see that the plot has made a little dip right at 4:00 UTC, so let's see if a flare is forthcoming, maybe in the morning just before sunrise. It's a small dip, and could simply be wander, but that's always the case. I might as well call the amplitude; I'll put it at C5.0. : ) Ok, that's just a guess. The one big flare I've monitored was preceded by a multi-hour dip (see the link below) but these little dips only last a couple of hours. They're all about the same amplitude, under 0.1%. That also makes me a little suspicious that it's just system wander.
I did post a lot of graphs here:
