New NOAA region 2685 (identical to returning region 2682, rotating into view at the East limb) is currently the only sunspot region on the solar disk as seen from Earth. Returning region 2683 produced a B3.3 flare from behind the East limb, peaking at 21:06 UT on October 21. A filament eruption near 20W 20N was observed in GONG and AIA images around 18:13 UT on October 21, apparently without corresponding Coronal Mass Ejection (CME). C flares are possible in the next 24 hours (55% probability), with a chance for an M flare (15% probability). No Earth-directed CMEs were observed in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal levels. Solar wind speed registered by DSCOVR increased from about 380 to a maximum of about 510 km/s around 2h UT on October 22, and then gradually decreased to current values around 430 km/s. The magnitude of the Interplanetary Magnetic Field (IMF) varied between about 2 and 12 nT, with current values around 3.5 nT. The IMF was directed towards the Sun and Bz had a negative excursion around -5 nT between about 21:30 and 23:30 UT. Quiet to active conditions (K Dourbes between 1 and 4; NOAA Kp between 1 and 3) were registered in the past 24 hours. Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on October 22, 23 and 24.
