I may be overloading the server by posting all these spectrograms, but I think it is important to document that the Sun was bursting almost continuously for several hours today.? Most of it was

I'm using a 21 MHz Moxon antenna tuned for 20 MHz, should be 3 dB better than a dipole. Not sure it is. Tom Crowley ________________________________ Sent: Friday, April 4, 2025 8:26 PM To:

Thanks Tom...Interesting in the differences in the spectrograms. I have a single dipole and a RSP1A receiver and nothing is calibrated. I would guess that for those REALLY interested in these events

Good evening:? ? ?More and more great solar. Thanks to Bill, Richard, Tom and Duane for the heads-up. John

Hi Solar Events Today. Salvador

Observations from Grafton, WV. Did not catch as much as others, but here is what I caught. ~Duane

This was the last strong event record but between the first 3 previously posted and this one there were 6 weaker events. After the 1821:40 event there were 5 more but much weaker. I haven't posted the

Hi All, Adding to the ever-growing pile, here are spectrograms from the Dark Sky Observatory of yesterday's solar events. Richard

Good evening...here are 3 events from this morning. Hopefully, there were more....bill...

Good evening again:? ? ?I accidently left out a solar from 04/03/2025. Sorry. Here it is. John

Good evening:? ? ?Another good solar day. Thanks to Salvador and Duane for the heads-up. John

Hi Solar events Today. Salvador

Looking back, I'm just going to chalk it up to RFI, as I can't seem to find any other indications matching the same times you have. Thanks for the quick response! [email protected]> wrote: -- G.

Hi Caleb, Are you referring to the signal that is present in your spectrograms at about 21.5 MHz?? That looks to me, unfortunately, to be some pretty typical RFI.? Check out the same time periods

Howdy Richard, A wonderful collection of captures from yesterday. I may have gotten some of the non-Io A, right around the same timeframe, but I'm honestly not sure if this is Jupiter or just RFI. If

Hi Folks, Here are some more spectrograms featuring solar bursts from 02 April 2025, most of which were posted by other observers.? Some of these also show Io-B emission.? In addition, the last

Here are some spectrograms of solar bursts on April 02 2025.? Some of these look pretty normal, but some look unusual.? Take a look at the last spectrogram between 17:26 and 17:36.? There are a

Hi All, Thanks for the head's up to all who posted those very nice images of solar on April 02.? Going over the data from our Dark Sky Observatory TFD4 array, I ran across this very nice combination
