Güneş Aktif Bölgeleri ve parlama

Solar flaring activity was moderate over the past 24 hours, with 2 M-class flares identified. A total of 5 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 847 (NOAA Active Region 4420) has the most magnetically complex configuration (Beta-Gamma-Delta). The largest flare was a M1.6 flare (SIDC Flare 7456) peaking on April 23 at 04:35 UTC, which was produced by SIDC Sunspot Group 825 (NOAA Active Regions 4397, 4419), which produced most of the flaring activity in the last 24 hours. The second- largest flare was a M1.2 flare (SIDC Flare 7457) peaking on April 23 at 04:59 UTC produced by SIDC Sunspot Group 847 (NOAA Active Region 4420). Solar flaring activity is expected to be moderate over the next 24 hours, with M-class flares likely and a small chance for X-class flares.

Koronal Kütle Atılımı

A Coronal Mass Ejection (CME) was observed LASCO-C2 data around 05:24 UTC on April 23. This CME is associated with M1.6 flare (SIDC Flare 7456) peaking on April 23 at 04:35 UTC, with a speed of around 800 km/s. A glancing blow arrival is expected on April 26 around 20:00 UTC.

Koronal delikler

SIDC Coronal Hole 157 (equatorial coronal hole extending to the polar south with a positive polarity) and SIDC Coronal Hole 156 (equatorial coronal hole with a positive polarity) are continuing to cross the central meridian.

Güneş rüzgarı

Slow solar wind conditions were recorded over the past 24 hours. The solar wind speed ranged between 432 km/s to 520 km /s. The total interplanetary magnetic field ranged from 3 to 6 nT, with the Bz reaching a minimum of -5 nT. The phi-angle was mainly in the negative sector (directed towards the Sun), with periods in the positive sector. Quite solar wind conditions are expected in the next 24 hours.

Jeomanyetizma

The geomagnetic conditions were quiet to unsettles (Kp 1-3 & K BEL 1-3) in the last 24 hours. Quiet to unsettled conditions are expected over the next 24 hours.

Proton akı seviyeleri

The greater than 10 MeV GOES proton flux was at background levels and is expected to remain at background levels over the next 24 hours.

Jeostatik yörüngedeki elektron akıları

The greater than 2 MeV electron flux, as measured by GOES-18 and GOES-19 was above the 1000 pfu alert threshold in the past 24 hours. The flux is expected to fluctuate around the alert threshold over the next 24 hours. The 24-hour electron fluence was at moderate levels over the past 24 hours and is expected to remain at these levels over the next 24 hours.
