Solar Active Regions and flaring

Solar flaring activity was moderate during the last 24 hours, with an M4 flare yesterday 23:44 UT from NOAA Active Region (AR) 3341 (magnetic type Beta, Catania group 40). The second brightest flaring event was a C4 from NOAA AR 3337 (magnetic type Beta, Catania group 43). Isolated M-class events are likely in the next 24 hours, mostly from NOAA AR 3341.

Espulsioni di massa coronale

No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours.

Vento solare

The Solar Wind (SW) conditions were typical of the slow SW regime during the last 24 hours. The SW speed gradually dropped from 470 km/h to about 400 km/h in the last 24 hours. The total interplanetary magnetic field (Bt) varied between 4 and 7 nT and its North-South component (Bz) ranged between -6 and 5 nT. The interplanetary magnetic field phi angle was predominately directed towards the Sun during the past 24 hours. The SW conditions are expected to remain in the slow SW regime in the next 24 hours.

Geomagnetism

Geomagnetic conditions were unsettled to quiet both globally and locally (NOAA Kp 2- to 3- and K BEL 2 to 3) during the past 24 hours. They are expected to remain in unsettled to quiet levels both globally and locally for the next 24 hours.

Proton flux levels

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.

Electron fluxes at geostationary orbit

The greater than 2 MeV electron flux was above the 1000 pfu threshold yesterday between 13:25 and 18:20 UT. It has remained below this level since and it is expected to remain below the threshold in the next 24 hours. The 24-hour electron fluence was at moderate levels from yesterday 14:15 UT until today 05:45 UT and at nominal levels for the rest of the past 24 hours. It is expected to remain at nominal levels for the next 24 hours.

Today's estimated international sunspot number (ISN): 221, based on 19 stations.
