There is S2 chorus occurring this morning in Colorado after a small dip in electron levels on Dec. 31st (http://sec.noaa.gov/rt_plots/elec_3d.html) It's nice...
Hi Shawn and all, I'd like to understand the physics of this better. I'll have a look at the graphs, but I think the sec data is from the GOES electron flux ...
Dear Listmembers! Finally I've started another project: The Cosmic Ray Muon Detector http://muon.captain.at/ Along with the project I created a yahoogroup...
Greetings, The following is another interesting note from the web: "Whistler mode waves in the form of ELF/VLF chorus, are generated by electrons injected into...

Greetings, There were S3-S4 whistlers this morning from 4:30-5:15 AM MST (11:30-12:15 UT) (several hours before sunrise. The whistlers nearly disappeared by...
Hi Thierry, I agree that the tweeks (which extend to upwards of 20 KHz) are not likely caused by receiver overload (although this is a possibility). The...

Hello everyone, I'm a new member of the group, thinking about purchasing a VLF receiver. Looks like there are several good, portable units available. My...
John, A half mile may be sufficient - How high a voltage do the power lines carry? Regular "distribution" level voltages shouldn't be a problem. High voltage...

Thanks for the reply, John. My electric utility says the lines I would be within 1/2 mile of are 12,470 volts, phase-to-phase / 7,200 v, phase-to-ground....
