Сонячно-активні області та спалахи

Solar flaring activity was low but frequent over the past 24 hours, with more than 10 C-class flares identified. SIDC Sunspot Group (SG) 870 (NOAA Active Region [AR] 4441, Beta magnetic configuration) and SIDC SG 873 (NOAA AR 4446, Beta magnetic configuration) produced all the C-class flaring activity. Notable flares are the SIDC flares 7771 (a C5 and the brightest flare that peaked on 23 May at 22:04 UTC) and the double-peaked flares 7769 (a C2 with its highest peak on 23 May at 19:55 UTC) and 7775 (a C3 with its highest peak on 24 May at 02:37 UTC). More C-flass flaring activity is expected in the next 24 hours.

Корональні викиди маси

No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours. The two CME seen in LASCO-C2/SOHO images as launched on 23 May at 16:12 and 19:12 UTC are back-sided events. The CME seen in LASCO-C2/SOHO images as launched on 24 May at 09:12 UTC is associated with SIDC SG 870 and was launched close to the west limb. None of the three CME is expected to affect Earth.

Сонячний вітер

The Solar Wind (SW) conditions of the past 24 hours feature a slow SW regime. The SW speed gradually dropped from 340 and 290 km/s, the interplanetary magnetic field (B) was between 3 and 6 nT, and its North- South component (Bz) varied from -4 to 4 nT. The SW conditions are expected to remain at the current levels in the next 24 hours.

Геомагнетизм

The geomagnetic conditions of the past 24 hours were at quiet levels both globally and locally (NOAA Kp 0+ to 1+ and K BEL 1 to 2). In the next 24 hours it is likely that they will continue at quiet levels.

Рівні потоку протонів

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

Потоки електронів на геостаціонарній орбіті

The greater than 2 MeV electron flux as, measured by GOES 19, was above the 1000 pfu alert threshold for past 24 hours. It reached a peak value of 4000 pfu on 23 May at 16:55 UTC. It is expected to remain at the same levels in the next 24 hours. The electron fluence was at moderate levels in the past 24 hours and it is expected to remain at the same levels in the next 24 hours.
