Morning sun, 27 July

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.
