Solar flaring activity was low and infrequent with two C1 flares detected during the past 24 hours. NOAA Active Region (AR) 3285 (Catania group 65) produced one of them, while a yet unnamed AR turning into Earth's view produced the second flare. More C-class flare activity is expected in the next 24 hours, most probably from the unnamed AR mentioned above.

No Earth-directed Coronal Mass Ejections (CME) were observed in the last 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.

The Solar Wind (SW) conditions were stable during the last 24 hours. The SW speed ranged between 490 and 570 km/s in the last 24 hours. The total interplanetary magnetic field (Bt) varied between 2 and 6 nT and its North- South component (Bz) ranged between -5 and 5 nT. The interplanetary magnetic field phi angle was directed away from the Sun until yesterday 19:00 UT and has turned towards the Sun since. The SW conditions will continue to be stable in the next 24 hours.

Geomagnetic conditions were globally quiet (Kp 3- or below) with two 3-hour intervals of moderate activity (Kp 3+). Locally the conditions were moderate yesterday (K BEL 3 at 15:00-00:00 UT) and quiet today (K BEL 1-2). Geomagnetic conditions are expected to remain quiet in the next 24 hours.
