Over the past 24 hours solar activity has been low. Four B-class flares have been recorded produced by the decaying NOAA Active Region (AR) 2660 and by the developing Active Region NOAA 2659 (McIntosh Class: Dsi, Mag. Type: Beta). One returning NOAA AR is expected to appear at the east solar limb in the next 24 hours. No earth-directed coronal mass ejections (CME) have been observed. The greater than 2 MeV electron flux measured by GOES reached high levels. Solar protons have remained at background levels. Solar activity is expected to remain low over the next 24 hours with a high chance of B-class flares and some probability of C-class flares.
The variations of the solar wind parameters were weak. Solar wind speed decreased from 370 km/s till 320 km/s during the last 24 hours. The magnitude of the Interplanetary Magnetic Field (Bt) remained below 5 nT. The Bz component fluctuated between between -3 and +3 nT. Geomagnetic conditions have been very quiet in the past 24 hours (K Dourbes between 0 and 2; NOAA Kp between 1 and 2). Geomagnetic activity is expected to continue at low levels today (26-May-2016). Active to minor geomagnetic storm conditions (Kp NOAA between 3 and 4) are possible from tomorrow 27-May-2017 due to the possible arrival of the 23-May-2017 CME.
Today's estimated international sunspot number (ISN): 026, based on 28 stations.
