25th July Sunspots and proms.

25th July. A blue sky although only average atmospheric conditions allowed me to capture some images of the Sun today. The first images was at 540 nm to show the sunspots and active regions (AR). The second and third images show the Sun in H alpha to show the prominences. There was a M1.5 flare at AR 3376. All single exposures with Canon 550d. Thanks for viewing.
