Yep, see the same thing. Guess we take the same meds.

Good evening to all...got a late start today (~1520 UTC, 1120 EDT) but here are two spectrograms.
The first at about 1611 UTC lasted for about 6 minutes contained at least 4 increasingly weak events. The oter at about 1927 UTC was quite strong.
...Hope I didn't miss more earlier in the day.
Best to one & all....bill....

Good evening one more time: ? ? ? IoA from 04/29/2025. RFI gets in the way somewhat. More thanks to Dr. Gray for the heads-up.

Re: Io-A May 1, 2025 Dark Sky Observatory
Thank you for the response Richard.? ?That is extremely helpful.? I'm 50 feet from the house, but next to my shed which is turning into my radio observatory.? It does have electric. I'll start the process of checking for interference.? Again, thanks for the help.?
Hi Peter,
?
Congratulations on getting your dual dipole up and running.? Jupiter-Io emissions should always look brighter than the background, never darker.? So, I don't think what you detected is indeed Jupiter.
?
What it does look like is that you have a serious case of RFI, but the good news is that when it turns off (21:09:50), it appears that you have quite a good relatively low RFI background.? If your antenna is near your house, the RFI probably comes from some electrical or electronics device that turns on and off automatically, say a heat pump or air conditioner or even your refrigerator.? If you can manage, turn every thing off, check your Radio Jove output, and then turn things back on one by one to try to determine which device is producing the noise.? Sometimes it is surprising.? I found that a small LED bedside lamp was causing lots of RFI for my home RadioJove setup.? Sometimes RFI comes from something your neighbor is running, and then you don't have so much control.?
?
The second spectrogram likewise shows RFI, this time one that turns on and off over a time frame of a few seconds.? That might be a garage door opener, for instance.? At our site at the Dark Sky Observatory, we have quite a low RFI background which helps to explain our good results.? We do, however, have a short burst of RFI when the observatory dome opens (and closes).? It looks a lot like your second spectrogram, although not nearly as pronounced.
?
I should also mention that Jupiter-Io is becoming progressively more difficult to observe with our setups as Jupiter moves into the daytime sky.??
?
Hopefully someone with more experience than me will chime in with some better ideas.
?
Best wishes,? Richard

Hi Duane,

I checked my output for that time (17:55:46) to see if I detected anything like that.? I did not.? I think what you saw may be some lightning.

Jim I agree the brain and eye sight is amazing.
That is reassuring, Larry.? Fascinating how the brain processes visual information.? My guess is that the brain is looking for a boundary and keeps failing to predict where it is.

Jim Sky, I can?see some?movement also?Jim. I think it must be our pupils?are constricting from the bright light area msking the illusion of movement?

Re: Io-A May 1, 2025 Dark Sky Observatory
Hello Everyone, A little help please.? Still a newbie.? My system is working, I have been getting solar flares, but still trying to get some?good Jupiter readings.? I monitored Io-A today and looking over what Richard found the best I?have is this match with his 21:09 readings (see attached).? Mine are dark spikes however.? Thoughts?? And if it's not - what am I missing?? Also attached a reading at 20:22:14 which is different, but haven't encountered this before.
Setup is a 10 foot dual dipole.? No phasing.? Graph is attached Appreciate it. Thanks- Peter
We saw a lot of Io-A this afternoon, but much of it was very faint.? I have posted the best bits from the RCP channel.
