Slunečně aktivní oblasti a vzplanutí

Solar flaring activity was moderate during the last 24 hours. Three M1 flares were detected, the first yesterday at 12:44 UT from NOAA Active Region (AR) 3341 (magnetic type Beta, Catania group 40), the second yesterday at 16:56 UT from NOAA AR 3337 (magnetic type Beta, Catania group 43), and the third today at 11:21 UT also from NOAA AR 3341. Isolated M-class activity is likely in the next 24 hours, mainly from NOAA AR 3341.

Vyhazování koronální hmoty

No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours. A full halo CME automatically detected by CACTus as launched yesterday 10:24 UT is judged to be two separate back- sided events.

Solární bouře

The Solar Wind (SW) conditions were typical of the slow SW regime and stable during the last 24 hours. The SW speed increased marginally and ranged between 450 and 490 km/s in the last 24 hours. The total interplanetary magnetic field (Bt) varied between 5 and 8 nT and its North-South component (Bz) ranged between -7 and 7 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.

Geomagnetismus

Geomagnetic conditions were unsettled to quiet both globally and locally (NOAA Kp 1 to 3+ and K BEL 2 to 3) during the past 24 hours. They are expected to drop to quiet levels both globally and locally for the next 24 hours.

Úrovně protonového toku

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.

Elektronové toky na geostacionární oběžné dráze

The greater than 2 MeV electron flux was marginally below the 1000 pfu threshold during the last 24 hours. For the next 24 hours it is expected to gradually drop further. The 24-hour electron fluence dropped from moderate to nominal levels yesterday 17:00 UT. It is expected to very gradually drop further in the next 24 hours.

Dnešní odhadovaný mezinárodní počet slunečních skvrn (ISN): 231, na základě 14 stanic.
