Note the detached plasma ejection off the Western limb (6 o'clock position) in the full-disk image. These massive salvos of ionized hydrogen can take on tremendous electro-magnetic potential as they snap free from the sun's surface, often reaching the power equivalent of a million 100-megaton bombs exploding simultaneously!

Image Info: Canon EOS 10D digital SLR,
Coronado Solarmax90/T-Max, and 30mm blocking filter attached to a Takahashi FS128 via T-mount TeleVue 4X Powermate (upper image) and at prime focus (lower image). Processing was done in Images Plus and final polishing in Adobe PhotoShop.
A 100,000+ mile hedgerow prominence line fires some 8 earth-diameters above the chromosphere on the Eastern limb, as even larger filaments wrap around Active Region 0471. North is 90 degrees CW of the prom in these images, taken in the late afternoon (20:15UTC) on 03-Oct-2003.
