lately. NOTHING.

Carl,
?
if you compare earlier of your spectrograms with today's,
you can see that the noise level is increasing. Isn't it
possible to rent a property for
your antenna?with
an electrical connection provided on the outskirts of the
city?

For more info on sprites on Jupiter you can google and lots of interesting info turns up. Tom

07 Apr 2025 Dawn and dusk
Neither in the morning nor in the evening was much airglow visible in the ionosphere. In the evening?before sunset, atmospheric discharges were clearly visible in the antenna's passband between 19.5 MHz and 22.5 MHz.
These were possibly local blue-sky discharges. The nearest thunderstorms at that time were over Sardinia in the Mediterranean (1300 km away), over Tunisia in North Africa (1600 km away), and Krasnodar on the Black Sea (2400 km away). These distances are normal in the VLF range, but appear to be quite unusual here on shortwave.

Re: 06 Apr 2025 Dawn and dusk
Sabine,
So impressed with your dawn/dusk! Wish I could see that here.? Mid month I will be moving up my band window to the center at 23Mhz. Well, after I do some antenna maintenance, as soon as the ground loses up.... Carl
Quite impressive patterns in the evening.

Thanks Dave, Still learning.? Jupiter was in the beamwidth of the dual dipole during the observation.? I am getting some good solar flares, but Jupiter being up in the daytime is often a problem?for me with interference?(some days are worse than others).? Thanks for the resource, and I appreciate your looking at the image. Peter
Hi Peter,
Sorry to say, I don't see any obvious Jovian DAM in your spectrogram.
That is indeed the location of Io-A on the phase plane -- but, where was Jupiter
in your sky at that time and where is your antenna beam pointing?
For examples of Jovian DAM and other emission, the people that post their
observations here are quite helpful.? Another resource is this presentation:

Thanks, Richard.? Smaller files over 24 hours via a schedule sounds like a good option to make the data chunks more manageable. ?
Has anyone had success using Radio Jupiter Pro to generate a schedule file based on event probability?? I suppose one caveat would be potentially missing other event types, such as Solar.
Thanks again,
Tyson
Hi Tyson,
?
Someone with more experience than I in the functioning of RSS may be able to help you get to the bottom of the error that you are encountering.? I suspect that either the file has been corrupted or that you are running into memory problems.? You might try recording a much shorter file and then try opening it in RSS.?? If that is successful, then try to increase the length of your recording.? If it is not successful, then you may have uncovered a bug in the program.
?
Because my setup is remote and we occasionally have power outages, I use a schedule file that records data in 6 hour blocks.? Each of those blocks uncompressed are about 220MB, which is a size that is much easier to handle and to scroll through than a 1GB file.? I think that most of us record our data during the day, and then, when the new day starts at 0h UTC we download the files and use RSS to scroll through them and so pick up the events that we then post.
?
Best wishes,? Richard Gray
