Powerful coronal mass ejections (CMEs) ripped from the Sun on 1 Sept. and again on 3 Sept. Both of rhese CMEs are not Earth-directed and each was from a different source region at and beyond the solar limb. The CME on 1 Sept. was measured at over 1,200 km/s (over 2,500,000 mph) and was associated with solar flare along the limb that peaked at R2 (Moderate) levels. The suspected source region has since rotated into view and is now AR3813. A far-sided CME burst out at similar speeds early on 3 Sept. however, the source region is unknown. Still, these CMEs were quite energetic as they led to enhancements in solar energetic particles here at Earth that led to the issuance of an S1 (Minor) solar radiation storm warning.

Sunspots and Solar Flares:
Seven sunspot clusters peppered the visible solar disk late on Tuesday and several of these regions remain quite capable of producing solar flares at the R1-R2 (Minor-Moderate) levels with a chance of R3 (Strong) events.
