Welcome to Radio JOVE 2.0 3

Dear Radio JOVE Community, The Radio JOVE Project is a NASA Partner citizen science project where participants purchase, assemble, and operate their own 16-24 MHz radio spectrograph to observe solar, Jupiter, Galactic, and Earth-based radio emissions. Learn to become a citizen scientist and contribute scientific-quality data to our data archive. Visit Getting Started to learn how to participate in Radio JOVE. Regards, The Radio JOVE Team

Solar May 31, 2025 from the Dark Sky Observatory 2

Adding to the contributions of others, here are the solar events of May 31 as seen from the Dark Sky Observatory. The first spectrogram shows wisps of solar arising from the M8 solar flare which began at about 0:00UTC. The third spectrogram shows hints of a SID beginning at about 15:45UTC. Richard

Solar activity M Class flare from AR4100 4

Hi, A lot of solar activity around the turn of the UTC Day. Large M-Class flare from AR4100. Solar observation from 23:36:00 – 02:15:12 First section of observation from 23:44:00 – 00:12:00 Latter section of observation from 00:12:00 – 02:04:00 Zoomed section showing fine Type II structure 23:48:45 – 00:00:00 Regards, Luke.

Independent Flares and Independent Radio Rursts 2

A flare can occur without producing radio bursts and solar radio bursts can occur without there being a flare. You said: A flare can occur without producing radio bursts and solar radio bursts can occur without there being a flare ChatGPT said: Yes, that's correct — and it's an important nuance in solar and space weather physics: 1. A flare can occur without producing radio bursts This happens when the flare's energy is primarily confined to thermal emissions (X-rays, EUV) and doesn’t accelerate enough high-energy electrons to generate detectable radio waves. Reasons include: The flare is weak or compact and doesn't inject electrons into open magnetic field lines. Magnetic confinement or geometry prevents electrons from escaping into the corona or interplanetary space. Instrument sensitivity or interference might obscure faint radio signals. 2. Solar radio bursts can occur without a visible flare This occurs because radio bursts are generated by nonthermal electron populations, which may originate from: Coronal mass ejections (CMEs) without associated flares (especially type II and type IV bursts). Active region dynamics like small-scale reconnection or magnetic restructuring. Noise storms or type I bursts, which are often long-lived and unrelated to discrete flares. Type III bursts from electron beams escaping along open field lines, which may occur without significant soft X-ray flare signatures. In summary: Not all flares produce radio bursts. Not all radio bursts come from flares. Both phenomena trace different aspects of solar magnetic energy release and particle acceleration.

Solar May 30, 2025 from the Dark Sky Observatory 2

Hi Folks, I am about a day behind posting these spectrograms, but better late than never! Lots of nice solar on May 30. I have only posted the more powerful events. Interestingly, I picked up (see the last image) what looks to be solar at the end of the "day", near 0:00 UTC, when the sun was well below the horizon. Take a look and see what you think. When the data are uploaded at the end of the day today (May 31), I will take a look and see if I got more of the below-the-horizon solar, presumably from the big M8 flare that started just before 0hr UTC May 31.
