X2.0 solar flare recorded yesterday around 11:00 by the Flamsteed VLF Receiver (see VLF plot under Observing). Could the source be the large sunspot/s observed on Saturday?

That's a great (inverse) correlation with the NOAA GOES data...

Yes, this is definitely coming from the active region where we can see the large sunspot. In fact, there have now been 6 X-class flares from this region... the latest at 14:47 this afternoon.

The flare picked up by the Flamsteed VLF receiver is the fifth in the sequence, peaking at 10:56 GMT on Sunday morning. And here it is, in all it's glory:

It's really interesting to note that not one of the X-class flares has produced a notable coronal mass ejection (CME). A real shame for aurora watchers.

It would seem that the layout of the active region means that it's not releasing plasma. I'm not sure I've seen such an active region, with so many X-class flares, and not one noteworthy CME to date.
