Solar flaring activity was low and infrequent during the last 24 hours, with NOAA Active Region (AR) 3467 (magnetic configuration Beta) producing the most and the brightest of the flares. The flaring activity is expected to remain low in the next 24 hours, with NOAA AR 3467 and a yet-unnamed AR at N28E88 producing most of the C-class flares.
No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours. Two CME observed by SOHO/LASCO-C2 yesterday at 04:36 and 16:36 UTC are estimated to be back-sided events.
During the last 24 hours the Solar Wind (SW) conditions returned to a typical slow wind regime. The SW speed dropped from a higher value of 520 km/s to 390 km/s and remains low. The total interplanetary magnetic field (Bt) remained up to 5 nT and its North-South component (Bz) ranged between -2 and 4 nT in the last 24 hours. The interplanetary magnetic field phi angle was directed away and towards the Sun for an approximately equal length of time. The SW conditions are expected to remain in the slow wind regime for the next 24 hours.
During the last 24 hours the geomagnetic conditions were both globally and locally quiet (NOAA Kp 2- to 0+ and K BEL 1 to 2) with the exception of unsettled conditions yesterday between 18:00-21:00 UTC (NOAA Kp 3- and K BEL 3). They are expected to remain quiet in the next 24 hours.
The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to remain so for the next 24 hours.
The greater than 2 MeV electron flux remained below the 1000 pfu alert threshold and is expected to remain below this threshold during the next 24 hours. The 24h electron fluence was at nominal levels and is expected to remain so.
Today's estimated international sunspot number (ISN): 101, based on 15 stations.
