Bülletään

Solar flaring activity was mostly at low levels over the last 24 hours with few C-class flares. Several active regions are on the solar disc visible from Earth. The magnetically complex bipolar regions Catania sunspot group 81 (NOAA active region 2993) and Catania sunspot group 82 (NOAA active region 2994) produced several C-class flares. The larger flare was produced from a new region just behind the East limb, this C6.8-class flare was associated with a coronal mass ejection in the South-East direction. For the next 24 hours, C-class flares are expected with still also a chance for an M-class flare.

No Earth directed Coronal Mass Ejection (CME) has been detected in the available coronagraph imagery over the last 24 hours.

The greater than 2 MeV electron flux remained below the 1000 pfu alert threshold and is expected to remain below the threshold in the next 24 hours. The greater than 2 MeV electron fluence was at nominal levels in the past 24 hours and is expected remained at nominal levels in the next 24 hours.

The solar wind parameters in Earth environment (as recorded by DSCOVR) showed a solar wind speed regime close to ambient background levels. The solar wind speed fluctuated around 400 km/s. The interplanetary magnetic field magnitude remained below 6 nT with a magnetic field orientation indicating connection to a positive polarity sector. Solar wind speed is expected to remain nominal over the next days.

The geomagnetic conditions were quiet (NOAA Kp and local K-Belgium 0-2) and are expected to remain quiet.
