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 C5.0 flare (SIDC Flare 4739) peaking at 12:23 UTC on June 23, which was produced by SIDC Sunspot Group 523 (NOAA Active Region 4114). A total of 6 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 527 (NOAA Active Region 4118) is the complex region with its beta-gamma 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 parameters are transitioning to slow solar wind regime. The solar wind speed ranged between 385 km/s and 480 km/s. The North-South component (Bz) ranged between -5 and 5 nT. The interplanetary magnetic field ranged from 1 nT to 7 nT. Enhanced solar wind parameters are expected in the next 24 hours with the arrival of high speed streams from the SIDC Coronal Hole 116 (negative polarity) which started to cross the central meridian on Jun 21.

Jeomanyetizma

Geomagnetic conditions were globally at quiet (NOAA Kp 1 to 2), and locally at quiet to unsettled conditions (K_BEL 1 to 3) during the past 24 hours. We expect unsettled to minor storm conditions (K 3 to 5) in the next 24 hours with the arrival of high speed streams from the SIDC Coronal Hole 116 (negative polarity) which started to cross the central meridian on Jun 21.

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.

Jeostatik yörüngedeki elektron akıları

The greater than 2 MeV electron flux, as measured by GOES-19, mostly remained below the threshold level, except from 14:00 UTC to 18:15 UTC on Jun 23, when it fluctuated around the threshold level. The greater than 2 MeV electron flux, as measured by GOES-18 satellite, reached above the threshold level at 16:00 UTC on Jun 23 and dropped below it at 02:45 UTC on Jun 24. 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.
