if you are familiar with this site check out the last 2 hours.
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.... Quoting: cosmicgypsy 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.
