20 Mar 2025 Teepees

#13105

Late out of bed, the ionosphere produces weak airglow and faintly indicated edges of teepees. In the evening, the teepees remain largely contourless due to weak edges.

Hi,

?

I picked up the same events as John.? Curiously, the 17:17 UTC event did not register very strongly here.? There were a few other very faint events that I did not bother to post.

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.

Cheers........Steve

Hello,

I may have picked up the 18:06 flare?(at least above 22 MHz) that Bill & Salvador recorded, did anyone detect a flare at 12:04?

Thanks John and you too Salvador.

?

Your spectrograms show, at a minimum, what a good antenna can do! And there must be better receivers than my RSP1A.

I will use them and revisit today's record to "see" what I didn't "see"!? :-)

?

It is sometimes possible with a bit of fancy image processing to reveal what my old eyes may have missed.

But there are limits.

?

Again, thanks to you both....bill

Good evening:

19 Mar 2025 Weak Teepees

#13091

The ionosphere had a bad start to the morning (sie kam nicht richtig aus dem Quark) and the exit from the stage was also rather weak.

Hi All,

?

The DSO TFD array recorded some faint non-Io-A earlier this evening, as well as a brilliant TP.

Thank you for the diagrams, Huub!

?

The free-space modeling result is quite reminiscent of the HB9CV antenna, with its pronounced null point on the back of the radiation pattern. This becomes significantly less apparent when setting up the antenna at a height of approximately 4 meters, as recommended by the RJ team for the dual dipole. However, the vertical pattern is then quite well adapted to the task.
