Markus It is definitely CFH, and is quite loud here at 700 km. I have been watching the line on your screen as well! Unfortunately, I'm not set up presently to make an accurate field strength reading
Markus, Curiosity took over, and I attempted a mid-afternoon measurement of the CFH carrier's field strength. I get 235 uV/M at 697 kM. A quick check with a great circle plot shows about 70% of that
