Zonnevlekkengebieden en zonnevlammen

Solar flaring activity over the last 24 hours has been at moderate levels, with multiple C-class flares and two M-class flares. The first was an M2.4 flare originating from NOAA active region 3716, peaking at 06:30 UTC on June 23. The second was an M1.3 flare originating from NOAA active region 3712, peaking at 11:37 UTC on June 23. Besides these two regions, there are five other sunspot groups on the disc showing C-class flaring activity. Solar flaring activity is expected to be at low to moderate levels over the next 24 hours, with C-class flares expected, M-class flares possible, and a small chance of X-class flares.

Coronale massa uitstoten

No Earth-directed CME was observed in SOHO/LASCO-C2 coronagraph images over the last 24 hours.

Zonnewind

Solar wind conditions initially returned to a slow solar wind regime in the last 24 hours. Around 00:00 UTC on June 23, some solar wind parameters became disturbed, reflecting the imminent arrival of the fast wind originating from the large north midlatitude coronal hole with negative polarity, which reached the central meridian on June 19. The interplanetary magnetic field reached up to 12 nT, and the Bz component varied between -11 nT and 8 nT. The solar wind speed remained below 375 km/s, and the phi angle turned to the negative sector. In the next 24 hours, solar wind conditions are expected to become more enhanced with the increase in solar wind speed.

Geomagnetisme

Geomagnetic conditions were quiet (NOAA Kp 0-2, K BEL 1-3). Later, active conditions to minor storms may be observed in response to the high-speed stream from the large north midlatitude coronal hole.

Proton flux niveaus

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

Elektronenfluxen in geostationaire baan

The greater than 2 MeV electron flux was below the threshold level in the last 24 hours and is expected to remain so over the next 24 hours. The 24-hour electron fluence is presently at normal levels and is expected to remain so over the next 24 hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 160, gebaseerd op 15 stations.
