Over the past 24 hours solar activity has been low. There have been seven B-flares flares originated at NOAA AR 2644 (McIntosh: Eso; Mag.Type: Beta), AR 2645 (McIntosh: Dki; Mag.Type: Beta). The biggest flare B5.0 peaked today (31-Mar-2017) at 03:46 UT. No Earth-directed CMEs have been detected over the past 24 hours. Solar protons have remained at background levels over the past 24 hours. Solar X-Ray background level is expected to remain low. NOAA AR 2645 and AR 2644 are expected to produce more B-class flares over the next 24 hours. C-class flares are also not excluded. NOAA AR 2645 has a small chance to produce M-class flare. Solar wind parameters remained enhanced. Total Interplanetary Magnetic field remained stable varying from 4 to 6.5 nT. Bz variations increased slightly (varying mostly between -6.1 nT to +6 nT). Over the past 24 hours, solar wind speed measured by DSCOVR increased from about 630 km/s to 730 km/s. Solar wind speed is expected to remain at high levels under CH HSS regime. The geomagnetic field was from unsettled to minor storm levels during the past 24 hours (K Dourbes between 2 and 4; NOAA Kp between 3 and 5). NOAA Kp index reached minor storm levels (Kp=5) at 21:00 UT yesterday, at 09:00 UT today (31-03-2017) Kp index returned to active conditions (Kp=4). The geomagnetic field is expected to continue at active levels for the next two days with few episodes of minor storming (Kp=5) in response to the agitated solar wind conditions.
Today's estimated international sunspot number (ISN): 059, based on 22 stations.
