Aktywne obszary słoneczne i rozbłyski

During the last 24 hours the solar flaring activity was moderate with an M1 flare produced by NOAA Active Region (AR) 3615 (magnetic configuration Beta-Gamma-Delta, Catania sunspot group 22) yesterday 22:55 UTC. The same AR produced all the C-class flaring of the last 24 hours and it has now started to decay. Isolated M-class flaring activity is possible in the next 24 hours, mostly from NOAA AR 3615.

Koronalny wyrzut masy

No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours. A partial halo CME launched yesterday at 17:36 UTC can been seen in LASCO-C2/SOHO images. It is estimated to be a back-sided event and hence not geo-effective.

Dziury koronalne

A southern, negative polarity Coronal Hole (CH) is currently crossing the solar central meridian. A High Speed Stream (HSS) associated with this CH is expected to affect the Earth's environment on Mar 24.

Wiatr słoneczny

During the past 24 hours the Solar Wind (SW) conditions were affected by the expected arrival of a Coronal Mass Ejection (CME) today at 01:50 UTC. The SW speed increased from 300 to 400 km/s as a result of the arrival, while the total interplanetary magnetic field (Bt) raised from 1 to 15 nT. The North-South magnetic component (Bz) ranged between -11 and 8 nT, while the interplanetary magnetic field phi angle changed from being directed towards the Sun to be directed away from the Sun. The effects of the CME are expected to wane in the next 24 hours and the conditions to return to a slow SW regime.

Geomagnetyzm

During the last 24 hours, geomagnetic conditions were globally and locally quiet to unsettled (NOAA Kp 0+ to 3+ and K BEL 1 to 3) as a result of the arrival of a Coronal Mass Ejection (CME) today 01:50 UTC. In the next 24 hours they are expected to drop to quiet levels.

Poziomy przepływu protonów

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is likely to remain so for the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, was at nominal levels during the last 24 hours and is expected to remain below this threshold during the next 24 hours. The 24h electron fluence was at very low levels during the past 24 hours and is expected to remain at these levels for the following 24 hours.
