Güneş Aktif Bölgeleri ve parlama

Solar flaring activity was low over the past 24 hours, with one C-class flare recorded. The largest flare was a C1.1 flare (SIDC Flare 7389), peaking at 10:24 UTC on April 11, associated with SIDC Sunspot Group 844 (NOAA Active Region 4416; magnetic type beta), a newly emerged and numbered active region near N19E10. There are currently three numbered active regions on the visible solar disk. SIDC Sunspot Group 842 (NOAA Active Region 4414; magnetic type beta) produced only B-class flares. Solar flaring activity is expected to remain low over the next 24 hours, with C-class flares likely.

Koronal Kütle Atılımı

No Earth-directed CMEs have been detected in the available coronagraph imagery over the past 24 hours.

Güneş rüzgarı

Over the past 24 hours, solar wind parameters (ACE and DSCOVR) reflected the ongoing influence of a high-speed stream (HSS). The solar wind speed increased from about 450 km/s to 700 km/s before gradually decreasing to around 500 km/s. The interplanetary magnetic field reached values up to 12 nT, and its north-south component ranged between -8 nT and 7 nT. The magnetic field orientation was predominantly in the positive sector (field directed away the Sun). Solar wind conditions are expected to remain slightly elevated over the next day while Earth remains under the influence of the high-speed stream. From April 13, a gradual transition to slow solar wind conditions is expected.

Jeomanyetizma

Geomagnetic conditions reached active levels both globally and locally over Belgium (NOAA Kp = 4, 4+; K-Bel = 4). Mostly unsettled to active geomagnetic conditions are expected over the next 24 hours due to the ongoing high-speed stream influence from a positive polarity coronal hole.

Proton akı seviyeleri

The greater than 10 MeV proton flux, as measured by GOES-18, was below the 10pfu 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, briefly exceeded the 1000 pfu alert threshold between 13:50 and 17:10 UTC on April 10 and remained below the threshold for the rest of the period. It is expected to exceed the alert threshold over the next 24 hours. The 24-hour electron fluence was at normal to moderate levels over the past 24 hours and is expected to remain at these levels over the next 24 hours.
