Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C3.4 flare (SIDC Flare 3903) peaking at 00:40 UTC on March 25, which was produced by SIDC Sunspot Group 450 (NOAA Active Region 4036). During the flare, the source region (SIDC 450) of the flare had beta-gamma configuration of its photospheric magnetic field. A total of 6 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 450 is the complex region with its beta-gamma magnetic configurations, which produced several C-class flares in the past 24 hours. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares very likely and a chance for M-class flares.

Koronalny wyrzut masy

No Earth-directed coronal mass ejections (CME) were detected in the available coronagraph observations during last 24 hours.

Dziury koronalne

SIDC Coronal Hole 96 (positive polarity, northern hemisphere) began to traverse the central meridian on March 25. SIDC Coronal Holes 60 and 82 (positive polarity) are still crossing the central meridian and the associated high speed streams are expected to arrive at Earth from March 25.

Wiatr słoneczny

Earth is presently inside the slow solar wind regime. The solar wind speed ranged from 340 km/s to 420 km/s and the interplanetary magnetic field ranged from 4 nT to 10 nT. The North-South component (Bz) ranged between -9 and 8 nT. Slow solar wind conditions are expected to continue over the next 24 hours unless the high speed stream from the coronal hole which started to cross the central meridian on Mar 22 (positive polarity) hits the Earth.

Geomagnetyzm

Geomagnetic conditions were globally and locally at quiet to active conditions (NOAA Kp and K_BEL 1 to 4). In the next 24 hours, active to moderate storm conditions (K 4 to 6) are possible if the high speed stream from the coronal hole which started to cross the central meridian on Mar 22 (positive polarity) hits the Earth.

Poziomy przepływu protonów

The greater than 10 MeV GOES proton flux was below the threshold level over the past 24 hours and is expected to remain so for the next 24 hours. However, a proton event over the next day cannot be excluded due to SIDC Sunspot Group 450 (NOAA Active Region 4036).

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by GOES-16 and GOES-18 satellites, remained below the 1000 pfu threshold level over the past 24 hours and is expected to remain so in the coming 24 hours. The 24h electron fluence is presently at normal level, and it is expected to remain so in the next 24 hours.
