Here's an alternative form of solar interference.
Screen grab of waterfall from my Wessex (ahem) KiWi web sdr showing spectrum from 0-60MHz earlier this afternoon.
There was much more severe burst of noise before I started the waterfall rolling, you can see this from the yellow peak hold line on the spectrum display at the top of the image.
I hastily added some time markers towards the top of the grab when I realised it wasn't a more usual fleeting solar event.
Looks like it was a genuine event, and not just local interference such as precipitation static, which sometimes occurs.

Anyone else see this ?
