This active region is now centered in the middle of visible solar disk what makes it geoeffective, so any Coronal Mass Ejection (CME) will be delivering solar plasma to our planet.

There are currently four numbered sunspots on the visible solar disk. AR 1875 is the most active and the biggest while other sunspots remain stable for now. AR 1875 already erupted three M-class and numerous C-class flares yesterday, and it looks like it will continue with high activity in the days ahead. NOAA/SWPC forecasters estimate 30% chance of an M-class and 5% chance of an X-class solar events in the next 24 hours. Forecasters also give 80% chance for high activity around AR 1875.
