What started as a nice clear, cloudless observing day quickly turned into something special. I didn’t expect to get this lucky, but this giant flare erupted from sunspot AR4392 right in view!
Both light and radio waves are part of the electromagnetic spectrum and travel at the speed of light. In this video, you can see the flare in H-alpha light and hear its radio emission, synchronized as both are coming from the same solar event. A radio receiver converts the radio waves into audio, allowing us to “hear” the Sun.
Radio instruments used:
• NASA’s Radio JOVE Single Dipole (20.1 MHz)
• Single Dipole (40 MHz) – same as above, but cut for 40MHz
• SuperSID Monitor (VLF 15–25 kHz)
The dipole antenna’s receive solar radio bursts from flares, while SuperSID monitors changes in Earth’s ionosphere caused by flares and ejections.
Timelapse sped up 250× — hours of solar activity in minutes.
If you are curious about how such an antenna looks like, check out this short appearance:

There will be an explainer video in the near future, featuring my radio setups.

That is amazing
