Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was very low over the past 24 hours. The X-ray flux was below C level. SIDC Sunspot Group 825 (NOAA Active Region 4436, Beta magnetic configuration) is currently rotating behind the west limb, however a large part of its flaring activity will continue to be detectable in the next 24 hours. Isolated C-class activity is likely during the next 24 hours.

Koronalny wyrzut masy

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

Wiatr słoneczny

The Solar Wind (SW) conditions of the past 24 hours feature a slow SW regime. The SW speed ranged from 410 to 510 km/s, the interplanetary magnetic field (B) was up to 5 nT, and its North-South component (Bz) varied from -5 to 5 nT. The SW conditions are expected to remain at the current levels in the next 24 hours.

Geomagnetyzm

The geomagnetic conditions of the past 24 hours reached unsettled levels both globally and locally (NOAA Kp 3 and K BEL 3) on 21 May from 00:00 to 03:00 UTC. The remaining time both global and local conditions were at quiet levels (NOAA Kp 1- to 2+ and K BEL 1 to 2). In the next 24 hours it is likely that they will continue at quiet levels.

Poziomy przepływu protonów

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.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux as, measured by GOES 19, was around the 1000 pfu alert threshold for past 24 hours. It reached a peak value of 1700 pfu on 20 May at 16:20 UTC. It is expected to marginally drop in the next 24 hours and possibly stay below the alert threshold. The electron fluence was at moderate levels in the past 24 hours and it is likely to drop to normal levels at some point in the next 24 hours.
