The Sun on June 18, 2022

 AR 3031, now approaching the Sun's limb, continues to show potential for M-Class flares. The the other spots appear to have stable magnetic fields. Several prominences are visible today and are captured on the overexposed image. The large filament is 370,000 km long--about the same distance as the Moon is from the Earth. Powerful plasma currents are flowing through it. One end is anchored in AR 3032, the other is not attached to anything, making a powerful CME a possibility if becomes unstable and erupts.
