On the 4th February 2025 Tony Razzell captured a couple of M class solar flares using his Very Low Frequency Sudden Ionospheric Detection system (described here). One M4.7 class flare occurred at 11:20 am and one M3.2 class flare (or possibly more than one concurrently as the shape is slightly different with a slower build-up) at around 13:10-13:14 pm. The GOES-16 satellite's X-Ray flux data is also shown for comparison.






Neil Garside captured this image of the Sun on the 2nd February 2025 using a Seestar S50 and Baader solar filter. Neil comments that the Baader filter appears to give much finer details than the stock filter that comes with the Seestar.  Image Credit: Neil Garside.
