Aktywne obszary słoneczne i rozbłyski

The solar flaring activity was at low levels with several C-class flares being detected in the last 24 hours. The largest flare was a C5.8 flare, peaking at 14:52 UTC on June 4th, associated with NOAA AR 3327 (beta class). NOAA AR 3323 (beta-gamma class) is currently the largest and most complex active region on the visible solar disc but produced only few C-class flares in the last 24 hours. Low flaring activity was also produced by NOAA ARs 3320 (beta class). Other regions on the disc did not show any significant flaring activity. The solar flaring activity is expected to be at low to moderate levels over the next 24 hours with a small chance for isolated X-class flare.

Koronalny wyrzut masy

A filament eruption occurred in the southwestern quadrant of the Sun from around 08:30 UTC on June 4th. The associated coronal mass ejection (CME) was observed in SoHO/LASCO C2 coronagraph data from 10:36 UTC on June 4th. The CME is directed to the south-west and the bulk of the CME is not expected to be Earth directed. However, a glancing blow of the shock may impact Earth in the late evening of June 07 or in the first half of June 08. In case of arrival, active geomagnetic conditions can be expected with possibly associated minor storm conditions. During the last 24 hours there were no other potentially Earth-directed CMEs detected in the available coronagraph observations.

Wiatr słoneczny

Over the past 24 hours the solar wind parameters (ACE and DSCOVR) were slightly elevated. The interplanetary magnetic field reached a magnitude of 12nT at around 16:50UTC on June 04. The solar wind speed increased slowly from values about 330 km/s to 430 km/s. The southward component of the interplanetary magnetic field fluctuated between -11 nT and 6 nT. Similar conditions can be expected for the next 24 hours.

Geomagnetyzm

During last 24 hours the geomagnetic conditions were at quiet to active levels (NOAA KP 1-4 and Local K Dourbes 1-4). Geomagnetic conditions are expected at quiet to unsettled levels during next days.

Poziomy przepływu protonów

Over the past 24 hours the greater than 10 MeV GOES proton flux was at nominal levels and is expected to remain so in the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux was below the 1000 pfu threshold and is expected to remain below this threshold for the next days.The 24h electron fluence was at normal level. The electron fluence is expected to be at normal levels in the next days.
