Moderate M1.6 solar flare erupted from Sunspot 1884 at 22:21 on November 2, 2013. Active Region 1884 is now located at the center of the visible solar disk and any strong eruptions can generate Earth-directed plasma cloud.
Few hours later, at 05:22 UTC on November 3, 2013 this region erupted M4.9 solar flare.
This region was responsible for an impulsive M6.3 flare on November 1, 2013. Active Region 1884 is currently only beta-gamma-delta class sunspot group and also the biggest sunspot group on the visible solar disk.
Active Region 1885 (located just beneath AR1884) produced a C8.2 flare at 04:46 UTC. No Earth-directed coronal mass ejections (CMEs) were observed through the day.
Earlier during the day, a moderate solar flare was detected around old sunspot 1875, which is now at the farside of the Sun. A full halo coronal mass ejection (CME) was detected by LASCO C2, but considering the location of the sunspot, there are no any danger to our planet.

There are currently 5 numbered sunspots of the Earthside of the Sun. Two new regions were numbered but remained unimpressive and stable. NOAA/SWPC forecasters estimate 35% chance of an M-class and 5% chance of an X-class solar flares in the next 24 hours.
