Active Region (AR) 2671 (McIntosh class: Fkc; Mag.type: Beta- Gamma) has shown some evidence of flux emergence in HMI magnetogram observations; however it produced only B-class flares over the past 24 hours. The largest flare among them was a B9.3 flare peaking at 07:40UT today. New active region 2672 (McIntosh class: Dao; Mag.type: Beta) has rotated into view from the eastern limb today and already produced three C-class flares. The largest flare was C5.9 flare peaking at 03:16 UT. No Earth directed Coronal Mass Ejections (CMEs) have been detected. The greater than 10MeV proton flux remained at background levels over the past 24 hours. There are no potentially geoeffective coronal holes on the Sun. More C-class flares are expected over the next 24 hours with some probability of M-class flares. The solar wind speed has decreased from around 730 to 570 km/s over the past 24 hours. The total magnetic field strength has remained below 5 nT. The Bz component fluctuated between -4 and +4.5 nT. The geomagnetic field was at active to unsettled levels; Kp NOAA index ranged between 2-3 and local K index (Dourbes) between 1 and 4. Mostly quiet to unsettled geomagnetic conditions are expected for the next few days.
