Some solar flares have been causing shortwave radio blackouts. The following images show the responsible sunspot groups. These images were taken early (8:40 am MDT). The sky was later covered by storm clouds for much of the day.
The telescope was an Astro-Tech AT102ED f/7 refractor with a Lunt solar wedge. The camera was an Olympus E-M5iii with a ND-0.6 filter, ISO 200, 1/1250 s.
