Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. SIDC Sunspot Group 423 (NOAA Active Region [AR] 4012, Beta-Gamma magnetic configuration) is the most complex AR and produced most of the flares. However, the brightest flare (a C3) came from S06E90 and might be a partially obscured back-sided event. During the next 24 hours the solar activity is expected to be at low levels, although there is a change for isolated M-class flare(s) either from SIDC Sunspot Group 423 or the AR at S06E90.

Koronalny wyrzut masy

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

Wiatr słoneczny

During the past 24 hours the Solar Wind (SW) conditions continued to be affected by the the High Speed Stream (HSS) that arrived on 8 Mar at 03:30 UTC. In contrary to the first indications, the HSS caused an increase of the SW speed which has now reached 720 km/s. The interplanetary magnetic field (B) peaked at 19 nT but now has dropped to approximately 10 nT. Its North-South component (Bz) registered values between -14 and 11 nT during the last 24 hours. The SW conditions are expected to remain at approximately the same levels during the next 24 hours.

Geomagnetyzm

The global geomagnetic conditions reached the moderate storm level (NOAA Kp 6-) on 9 Mar at 03:00-06:00 and 09:00-12:00 UTC. They were previous at minor storm level (NOAA Kp 5-) from 8 Mar 18:00 UTC to 9 Mar 03:00 UTC. The increased conditions were the result of the High Speed Stream (HSS) on 8 Mar at 3:30 UTC. They are expected to remain at storm levels for the next 24 hours. Locally the geomagnetic conditions were milder, with minor storm levels (K BEL 5) registering on 8 Mar at 21:00-24:00 UTC. They are expected to follow a similar pattern during the next 24 hours.

Poziomy przepływu protonów

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. Nevertheless, there is a small chance that a proton event might occur during the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by the GOES-18 satellite, peaked close but below the 1000 pfu alert threshold. For the next 24 hours it is expected to continue fluctuate a lot and peak below but close to the threshold. The 24h electron fluence remained at normal levels during the past 24 hours. It is expected to remain at normal levels for the next 24 hours.
