Quoting: Thoth's Thought Form I do wish I understood what was happening with this graph. I look at it, I want to know how it works, but I can't figure it out. If you have the time, Thoth's, could you give me a little learning lesson about this? Heh, to me they look like scientists abstract art....  But I want to learn how it's monitoring and what all the moving lines mean....ya know, the whole story....in short. Good to see you, lovey and my heart to yours....  Thank you CG. When a meteor enters the Earth's upper atmosphere it excites the air molecules, producing a streak of light and leaving a trail of ionization (an elongated paraboloid) behind it tens of kilometers long. This ionized trail may persist for less than 1 second up to several minutes, occasionally. Occurring at heights of about 85 to 105 km (50-65 miles), this trail is capable of reflecting radio waves from transmitters located on the ground, similar to light reflecting from a mirrored surface. Meteor radio wave reflections are also called meteor echoes, or pings. In order to listen to meteor echoes, you need a powerful transmitter in VHF band (ideally a tower broadcasting analog TV on a channels 2-5) located not too close but not too far either from you, a TV antenna, a VHF receiver... and patience. until this year. normally its not this strong. Ahhh, thank you! Now I know!....  learning IS fun. That's just me reflecting on something I posted yesterday. So the red lines jumping up and down like that are notations of this ionized trail, or is the the top one, the pale blue-lilac lines?...boy howdy, I hope I asked that right.... Hmmm, perhaps I should ask what those different graphs are "saying" about the meteors...looking at it now while typing, the top one is monitoring for the "sounds" and the bottom one is showing when and how long they are in the atmosphere....I suppose, reflecting the radio waves...how long they're at "play"? Correct me if I'm wrong, okay?....
