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 C5.2 flare (SIDC Flare 3895) peaking at 07:37 UTC on March 24, which was produced by SIDC Sunspot Group 412 (NOAA Active Regions 4002, 4035). During the flare, the source region (SIDC 412) of the flare had beta configuration of its photospheric magnetic field. A total of 8 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 450 (NOAA Active Region 4036) is the complex region with their beta-gamma magnetic configurations. 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

All CMEs detected in the available coronagraph observations during the last 24 hours were narrow and not Earth-directed.

Dziury koronalne

SIDC Coronal Holes 82 (positive polarity) began to traverse the central meridian on March 24, and the SIDC Coronal Holes 60 (positive polarity) is still crossing the central meridian. The associated high speed streams are expected to arrive at Earth from March 25.

Wiatr słoneczny

Over the past 24 hours, the solar wind parameters were disturbed under the influence of an interplanetary coronal mass ejection (ICME) that departed the Sun from Mar 21. The solar wind speed ranged between 345 km/s to 440 km/s. The North-South component (Bz) ranged between -10 and 13 nT. The interplanetary magnetic field ranging from 4 nT to 17 nT. The solar wind speed may increase if the high speed stream from the coronal holes, which crossed the central meridian on Mar 19 (negative polarity) and Mar 22 (positive polarity) hits the Earth in the coming 24 hours.

Geomagnetyzm

Geomagnetic conditions were quiet to active conditions (NOAA Kp and K_BEL 1 to 4) both globally and locally, due to impact of ICME that departed the Sun from Mar 21. In the next 24 hours, we expect to see active conditions if the high speed stream from the coronal holes, which crossed the central meridian on Mar 19 (negative polarity) and 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.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, was below the 1000 pfu threshold level over the past 24 hours. However, greater than 2 MeV electron flux, as measured by the GOES-18 satellite, reached above the threshold level at 20:15:50 UTC on Mar 23 and dropped below the threshold level at 22:00 UTC on Mar 23. The electron flux is expected to remain below the threshold in the coming 24 hours.
