Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was low over the past 24 hours, with several C-class flares recorded. The largest flare was a C2.4 flare (SIDC Flare 7394), peaking at 05:08 UTC on April 12, associated with SIDC Sunspot Group 845 (NOAA Active Region 4417), a newly emerged and numbered active region near S06W74. There are currently three numbered active regions on the visible solar disk. The remaining active regions are relatively simple (magnetic type alpha or beta) and did not produce any significant flaring activity. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares very likely and a small chance for M-class flares.

Koronalny wyrzut masy

No Earth-directed CMEs have been detected in the available coronagraph imagery over the past 24 hours.

Dziury koronalne

A mid-latitude positive polarity coronal hole (SIDC Coronal Hole 159) in the southern hemisphere started to cross the central meridian from late on April 11.

Wiatr słoneczny

Over the past 24 hours, solar wind parameters (ACE and DSCOVR) reflected the waning influence of a high-speed stream (HSS). The solar wind speed decreased from about 600 km/s to 500 km/s. The interplanetary magnetic field remained weak, below 8 nT, and its north-south component (Bz) fluctuated between -4 nT and 4 nT. The magnetic field orientation was predominantly in the positive sector (field directed away from the Sun). Enhanced solar wind conditions, with a gradual return to the slow solar wind regime, can be expected over the next 24 hours, under the waning influence of the high-speed stream.

Geomagnetyzm

Geomagnetic conditions were quiet both globally and locally over Belgium (Kp 1 to 2 and K-Bel 1 to 2). Mostly quiet to unsettled conditions are expected over the next 24 hours.

Poziomy przepływu protonów

The greater than 10 MeV proton flux, as measured by GOES-18, was below the 10pfu threshold level over the past 24 hours and is expected to remain so for the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by GOES-19, remained below the 1000 pfu alert threshold over the past 24 hours. The greater than 2 MeV electron flux, as measured by GOES-18, briefly exceeded the 1000 pfu alert threshold between 17:00 UTC and 23:20 UTC on April 11 and remained below the threshold for the rest of the period. It is expected to remain mostly below the alert threshold over the next 24 hours. The 24-hour electron fluence was at normal to moderate levels over the past 24 hours and is expected to remain at these levels over the next 24 hours.
