Zonnevlekkengebieden en zonnevlammen

Solar flaring activity was low over the past 24 hours. There are currently 8 numbered regions on the disk. The largest flare was a C4.7 flare (SIDC Flare 7868) peaking on June 05 at 22:45 UTC, which was produced by SIDC Sunspot Group 890 (NOAA Active Region 4462). This region exhibited flux emergence over the period and has magnetic type beta. 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) continued to decrease in size and simplify slightly but remains a complex region (magnetic type beta-gamma). SIDC Sunspot Group 884 (NOAA Active Region 4456) that reemerged on June 05 continues to grow and now has Beta-Gamma magnetic configuration. The remaining regions are stable and mostly quiet. 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.

Coronale massa uitstoten

No new Earth directed Coronal Mass Ejections (CMEs) were detected the available coronagraph imagery.

Coronale gaten

A small mid-latitude coronal hole in the southern hemisphere with positive polarity (SIDC Coronal Hole 159) began to transit the central meridian on June 06.

Zonnewind

Over the past 24 hours, the solar wind parameters reflected the ongoing ICME influence. At the start of the period the magnetic field increased to a maximum strength of 20 nT at 12:30 UTC June 05. The magnetic field strength then decreased gradually and is now stable at 5 nT. The solar wind speed ranged between 540 and 730 km/s and is now around 600 km/s. The ICME influence is expected to gradually wane over the next 24 hours.

Geomagnetisme

Geomagnetic conditions reached moderate storm conditions. NOAA KP reached 6+ between 15:00 and 18:00 UTC and K-BEL reached 6 between 17:00 and 19:00 UTC on June 05. This was in response to the ongoing ICME passage. The geomagnetic conditions were at quiet to unsettled levels globally and locally (NOAA Kp and K Bel 1-3). Active to minor storm conditions are expected over the next 24 hours due to the ongoing ICME influence.

Proton flux niveaus

The greater than 10 MeV proton flux 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.

Elektronenfluxen in geostationaire baan

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