While all eyes have been on sunspots, I for one have been monitoring this large filament channel now directly facing Earth. A series of dense, plasma filled filaments stretching over 500,000 km remains magnetically anchored in place for now. Should one of more of these

The storm has subsided for now, but for how long. DSCOVR solar wind speed data just showed a jump from 812 km/s to just over 900 km/s which could be signs of another expected shockwave about to pass Earth. A geomagnetic storm watch remains in effect for the next 24-48 hours.

A comparison of AR 3664 on May 13th as it approached the southwest limb and on May 29th as it returns into view off the southeast limb. Clearly the region shrunk in size while transiting the farside of the Sun, however it retains some magnetic complexity and will remain a threat

Just when you think AR 3664 is running out of steam, it produced an X1 solar flare at 16:26 UTC (May 12). The region continues to move closer towards the west limb. Any eruptions at this point should be directed mostly away from Earth.
