Re: Solar Event 22 March 2025, Prospect, ME
It could have been a close-by radio transmitter which saturated and desensed the receiver.

Thanks Sabine but highly unlikely it is a bad coax connection...it lasted only 20 seconds and spectrogram returned to normal and whatever it was never occurred again.
?
Thanks for looking John..the solar event report showed nothing anomalous for that time...

March 14 2025 total eclipse ??? - Heliotown
Hmmmm.
I wonder if my spectrograms show the total lunar eclipse on March 14, 2025?
It had its penumbral phase starting at 03:57 UTC and partial phase
starting at 05:09 UTC , and totality starting at 06:26 UTC and ending at
07:31 UTC.
Two spectrograms attached.
Anyone else show this coincidence? - Tom

Re: 22 Mar 2025 Dead Band Heliotown
Thanks Tom. Yours looks pretty devoid of background band noise in the post-dawn hours as well.

Today there was very little band noise in the morning (1200-1700 UTC ).
SWPC did
not report any X-ray flares. Also, the preceding day's band noise took
longer
than usual to decay. Was there a CME impact to the geomagnetic field today
or
yesterday? The K-index was high, but was it CME-impact high? Something
of a
mystery. Spectrograms from the 17th through 21st show the normal sunrise
onset
of band noise propagation.

Re: Solar Event 22 March 2025, Prospect, ME
Hi Bill,
?
it looks more like a bad connection at the antenna feed point or at a connector. Anything with hard edges in the spectrogram is suspicious.

22 Mar 2025 Early ionospheric degradation before sunset (Europe)
Dave already pointed this out: Something was strange within the ionosphere during the day. The band noise was low and the teepees were already there before sunset.

Re: Solar Event 22 March 2025, Prospect, ME
Bill: ? ? ?Here is my two cents. I looked at SkyPipe 20.1 MHz and did not see a signal dropout. With that said, your data seems to show some dropout ?from 16:19:40 to 16:20:20. With my knowledge I cannot be definitive. Recommend letting the pros take a look. It will be interesting to see what they have to say. Thanks.

Hi John,
Here is the SWPC log for March 20th.? There was a type 3 burst exactly 1 hour before at 11:04 UTC, and another 50 minutes later at 12:54, but nothing at 12:04.? And since no one else picked it up, the logical conclusion is that my 12:04 event below is just RFI.

Hi John.
You got a really strong one at 18:06 at the same time as my lone result below.....but you also got others in quick succession around that time that I did not detect.? So either the RFI in my area is so bad that only the strongest signal got detected, or I just happened to get a really strong RFI burst at the same time the rest of you got a genuine signal.
Unfortunately you did not record anything at 12:03.? I will check the SWPC results once they come available to see if they recorded anything.
