Сонячно-активні області та спалахи

Solar flaring activity was low over the past 24 hours, with 10 C-class flares identified. All but one of those flares were emitted by SIDC Sunspot Group (SG) 836 (NOAA Active Region [AR] 4405, Beta magnetic configuration), with SIDC SG 832 (NOAA AR 4403, Alpha magnetic configuration) producing the other one. The brightest flare of the past 24 hours was SIDC flare 7277, a C5, and is associated with SIDC SG 836. It should be noted that this is a very long duration event, not exclusively associated with SIDC SG 836, and has released energy comparable to an M-class flare. C-class flaring activity is expected in the next 24 hours, with a chance of an isolated M-class flare.

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

Сонячний вітер

The Solar Wind (SW) conditions of the past 24 hours resemble the slow SW regime. The SW speed registered values between 380 and 520 km/s, the interplanetary magnetic field (B) ranged between 1 and 6 nT, and its North-South component (Bz) varied from -5 nT to 4 nT. A High Speed Stream (HSS), associated with the crossing of the SIDC Coronal Hole (CH) 156 of the Solar central meridian on 25 Mar, is expected to affect the SW conditions in the next 24 hours.

Геомагнетизм

The geomagnetic conditions of the past 24 hours were both globally and locally at quiet to unsettled levels (NOAA Kp 2- to 3+ and K BEL 1 to 3). A HSS is likely to arrive in the next 24 hours and increase the conditions to active levels.

Рівні потоку протонів

The greater than 10 MeV proton flux, as measured by the GOES-19 satellite, was at background levels over the past 24 hours and is likely to remain so in the next 24 hours.

Потоки електронів на геостаціонарній орбіті

During the past 24 hours, the greater than 2 MeV electron flux as measured by GOES 19 dropped marginally but remained above the 1000 pfu alert threshold and ranged between 1000 and 10000 pfu. A further drop is expected, however it is likely that the electron flux will remain above the alert threshold level for most of the next 24 hours. The electron fluence was mostly at moderate levels in the past 24 hours and increased to high levels on 26 Mar between 18:05 and 21:25 UTC. It is expected to remain at moderate levels in the next 24 hours.
