Güneş Aktif Bölgeleri ve parlama

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C3.4 flare peaking at 05:47 UTC on June 23, which was produced by a back- sided sunspot group on the NW limb. A total of 5 numbered sunspot groups were identified on the disk over the past 24 hours. Four sunspot groups (SIDC Sunspot Groups 522, 523, 526, and 527) have beta magnetic configurations. The 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 probable, and a small chance of X-class flares.

Koronal Kütle Atılımı

No Earth-directed coronal mass ejections (CME) were detected in the available coronagraph observations during last 24 hours.

Koronal delikler

SIDC Coronal Hole 116 (negative polarity), which spans from 20 S to 30 N, is still crossing the central meridian. The high speed stream from this coronal hole are expected to enhance the solar wind environment near Earth on Jun 24-25.

Güneş rüzgarı

Solar wind conditions are transitioning from fast to slow solar wind. The solar wind speed ranged from 355 km/s to 530 km/s. The North- South component (Bz) ranged between -6 nT and 5 nT. The interplanetary magnetic field ranged between 3 nT and 7 nT. In the next 24 hours, we expect a transition to slow solar wind conditions unless the high speed stream, from the SIDC Coronal Hole 116 (negative polarity) which started to cross the central meridian on Jun 21, arrives earlier at Earth.

Jeomanyetizma

Geomagnetic conditions were at quiet to unsettled conditions (NOAA Kp 1 to 3) both globally and locally. We expect quiet to unsettled conditions (K 1 to 3) in the next 24 hours unless the high speed stream, from the SIDC Coronal Hole 116 (negative polarity) which started to cross the central meridian on Jun 21, arrives earlier at Earth.

Proton akı seviyeleri

The greater than 10 MeV GOES proton flux was below the threshold level over the past 24 hours and is expected to remain so for the next 24 hours. If any major flare occurs from SIDC Sunspot Group 523 (NOAA Active Region 4114), which is presently closer to the W limb, it could possibly be associated with a proton event in the coming hours.

Jeostatik yörüngedeki elektron akıları

The greater than 2 MeV electron flux, as measured by GOES-19, remained below the 1000 pfu threshold level over the past 24 hours. The greater than 2 MeV electron flux, as measured by GOES-18 satellite, mostly remained below the threshold level, except from 17:45 UTC to 22:30 UTC on Jun 22, when it fluctuated around the threshold level. In the next 24 hours, the electron flux is expected to remain below the threshold level, but increasing above the threshold level cannot be excluded. The 24h electron fluence is presently at normal level, and it is expected to remain so in the next 24 hours.
