The Sun 13-6-09 - Large arch prominence in NE

Only had a short time to image the sun today, but the brief view was worth the effort as there was a large arch prominence on the NE limb. No active regions visible in Ha light but AR11020 is over on the west limb now and extremely small. I am amazed this tiny flux area got an NOAA designation as it was very weak and had no strong spots.
