Re: 10 Mar 2025 Doubtful Io-B and real TPs
Hi Andy, Weird stuff does happen, so it's often unwise to speak in absolutes. However, in our experience: Sabine's spectrogram shows a couple nested TPs with skip-focused edges (the slightly hotter

Re: 10 Mar 2025 Doubtful Io-B and real TPs
Sabine, Could that be Cassiopeia A scintillation instead of a TP? Cass A RA is at transit at your location at 17:00 UTC. Best wishes, Andy [email protected]> wrote:

10 Mar 2025 Doubtful Io-B and real TPs
It would take a lot of imagination to pass the spots off as Io-B. But the TPs are real and really beautiful! Sabine -- Germany Standard time: UTC +1 hour

Re: How much do your calibrations vary?
Jim To be honest Jim I¡¯ve been working on taxes every spare minute. Think I¡¯m close to finished. But I can barely see any thickness in the plot. I need to move the calibrator over to a different

Spectrograms have been nothing but lightening strikes for hours. Very large storm in Florida, Georgia, and South Carolina (about 1100 miles southeast from Prospect, ME) and small storms west of the

Hi Dave, Thanks for those interesting comments.? I am still just at the beginning of understanding the nuances of ionospheric propagation and, for that matter, the mechanisms behind Jupiter-Io DAM

Re: How much do your calibrations vary?
Jim Yes good idea Jim. I have voltage regulators on each calibrator voltage line, 12v, 5v, and 3.3v and I can tell you they do drift slightly over months of time. Have not charted that but might be

Re: Some non-Io-A from tonight March 09 2025
Very nice non-Io-A, Richard. The increasing frequency circa 2244 to 2252 UTC is interesting. That may say more about the ionosphere than the arc shape. Non-Io-A is always vertex late (negative freq
