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 number of emission "events" which are fairly narrow-band, but do not appear like normal human-caused RFI.? These events can be seen in both polarization channels, and so are presumably not Jupiter-Io.? Did anyone else see these features?
