太陽活動區和耀斑

Solar flaring activity was low over the past 24 hours, with a few C-class flares identified. SIDC Sunspot Group (SG) 835 (NOAA Active Region [AR] 4404, Alpha magnetic configuration) produced the brightest flare (SIDC flare 7284, a C2, that peaked on 28 Mar at 21:10 UTC). SIDC SG 830 (NOAA AR 4401, Beta-Gamma magnetic configuration) and SIDC SG 836 (NOAA AR 4405, Beta-Gamma magnetic configuration) also emitted X-ray flares. In the next 24 hours, C-class flaring activity is expected, although isolated M-class activity is still possible.

日冕物質拋射

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

太陽風

The Solar Wind (SW) conditions of the past 24 hours are typical of the slow SW regime. The SW speed registered values between 330 and 400 km/s, the interplanetary magnetic field (B) ranged between 2 and 8 nT, and its North-South component (Bz) varied from -5 nT to 2 nT. Slow SW conditions are expected to continue in the next 24 hours.

地磁

The geomagnetic conditions of the past 24 hours were both globally and locally at quiet to active levels (NOAA Kp 2- to 4- and K BEL 2 to 4). In the next 24 hours it is likely that they drop to unsettled levels, although there is chance of activate levels to still register.

質子通量水平

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 expected to remain so.

地球靜止軌道上的電子通量

During the past 24 hours, the greater than 2 MeV electron flux as measured by GOES 19, fluctuated around the 1000 pfu alert threshold. A small drop is expected in the next 24 hours. The electron fluence dropped from moderate to normal levels on 29 Mar at 00:50 UTC. It is expected to remain at normal levels in the next 24 hours.
