Solaraktive Regionen und Flares

Solar flaring activity was moderate over the past 24 hours. There are currently 8 numbered regions on the disk. The largest flare was a an M1.8 flare (SIDC flare 7874), with peak time June 06 at 14:01 UTC, from SIDC Sunspot Group 889 (NOAA Active region 4461) in the south-east quadrant. However, this region remains a simple region (magnetic configuration beta). SIDC Sunspot Group 884 (NOAA Active Region 4456) continued to grow and now has Beta-Gamma-Delta magnetic configuration and is the most complex region on disk. SIDC Sunspot Groups 887 and 886 (NOAA Active Regions 4459 and 4458) were mostly stable with magnetic type beta. Sunspot Group 860 (NOAA Active Region 4455) decreased in complexity and now has magnetic type beta. Sunspot Group 891 (NOAA Active region 4464) grew over the period. Solar flaring activity is expected to be moderate over the next 24 hours, with C-class flares expected and isolated M-class flares probable with a chance for X-class flares.

Koronaler Massenauswurf

An asymmetric halo Coronal Mass Ejection (CME) to the south-east was detected in SOHO LASCO-C2 starting at June 06 at 14:01 UTC. This CME was associated with the M1.8 flare (SIDC flare 7874). This event was also associated with a Type II radio emission. The CME is also seen in STEREO-A COR2 data and initial analysis indicates that this CME will have an Earth directed component with a likely arrival in the second half of June 08.

Sonnenwind

Over the past 24 hours, the solar wind parameters reflected the ongoing waning ICME influence. The magnetic field strength was stable at 5 nT. The solar wind speed decreased from around 630 and 540 km/s. The solar wind speed is expected to continue to gradually decrease on June 07. An enhancement in the solar wind parameters is expected from the second half of June 08 in response to the arrival of the CME from June 06 (SIDC CME 672).

Geomagnetismus

Geomagnetic conditions were at quiet to unsettled conditions (NOAA KP 2-3) with one isolated period of active conditions locally (K-BEL 4). Quiet conditions are expected on June 07 with moderate to major storm conditions possible from June 08 due to the expected CME arrival.

Protonenflusswerte

The greater than 10 MeV proton flux increases slightly but was below the 10 pfu threshold over the past 24 hours. It is expected to remain below this threshold level over the next 24 hours.

Elektronenflüsse im geostationären Orbit

The greater than 2 MeV electron flux, as measured by GOES-18 and GOES-19, was below above 1000 pfu threshold. The greater than 2 MeV electron flux is expected to be above this threshold over the next 24 hours. The electron fluence was at normal to moderate levels and is expected to be at moderate levels for the next 24 hours.
