Slunečně aktivní oblasti a vzplanutí

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. SIDC Sunspot Group 368 (NOAA Active Region [AR] 4006, at N19W49, Beta magnetic configuration) has produced the brightest flare, a C3 on 4 Mar at 00:52. SIDC Sunspot Group 423 (NOAA AR 4012, at S13E47, Beta-Gamma magnetic configuration) also produced a significant number of C-class flares. SIDC Sunspot Group 416 (NOAA AR 4007, at S10W44, Beta-Gamma-Delta magnetic configuration) is magnetically the most complex on disk and is expected to increase its activity significantly in the next 24 hours. Further C-class flaring is expected, however increased activity to M-class level is also possible in the next 24 hours.

Vyhazování koronální hmoty

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

Solární bouře

The Solar Wind (SW) conditions resembled the slow SW regime during the last 24 hours. The SW speed fluctuated between 420 and 560 km/s, while the interplanetary magnetic field (Bt) ranged between 2 to 9 nT in the last 24 hours. Its North-South component (Bz) registered values between -5 and 7 nT during the same period. Slow SW conditions are expected in the next 24 hours.

Geomagnetismus

During the last 24 hours geomagnetic conditions were globally and locally quiet (NOAA Kp 1- to 2+, K BEL 2). In the next 24 hours they are expected to remain quiet both globally and locally.

Úrovně protonového toku

The greater than 10 MeV proton flux, as measured by the GOES-18 satellite, was at nominal levels over the past 24 hours and is likely to remain so in the next 24 hours.

Elektronové toky na geostacionární oběžné dráze

The greater than 2 MeV electron flux, as measured by the GOES-18 satellite, reached but did not exceed the 1000 pfu threshold during the past 24 hours. For the next 24 hours it is expected to remain at this level and not exceed the said threshold. The 24h electron fluence reached the moderate levels over the past 24 hours. It is expected to marginally decrease to normal levels over the next 24 hours.
