Full Disk H-alpha image March 10
This is a full disk H-Alpha image taken March 10. Active area 1429, which continues to produce X-Class flares (the most energetic the Sun produces) is visible as a light area to the left of center. On the right limb of the disk, a prominence is faintly visible a little above the 3 o'clock position.
