8/4/2019 AR 2738 large sunspot.

Not the best of seeing , light cloud didn’t help. But a welcome huge sunspot. Resolved by eye , it gave four near joined black areas with a large penumbra. Plenty of surface detail.

Got this using a Lunt Herschel wedge and a polarising filter in a Vixen 90mm. By eye there was also a smaller spot nearer the limb. Ha gave a huge hedgerow prom. This is a B solar flare event , those to the north will be happy to get auroras.

clear skies ! Nick.
