AR 1818 After Flare and Prominence

After a long, cloud-enforced hiatus, I had both free time and (relatively) clear skies coincide today. The images of AR 1818 show it about 40 minutes after a significant M-3 Class flare. As you can see, it is very bright in H-Alpha. The other image shows detail of a lovely prominence on the sun's edge near the active area. Imaged with PST-SolarMaxII and LifeCam.
