Güneş Aktif Bölgeleri ve parlama

Solar flaring activity was at low levels over the past 24 hours with background C-class flaring. A total of 9 numbered sunspot groups were identified on the visible solar disk. The most complex regions are SIDC Sunspot Group 461 (NOAA Active Region 4048) and SIDC Sunspot Group 469 (NOAA Active Region 4055), both classified as beta- gamma. SIDC Sunspot Group 469, together with the newly rotated region from the east limb, contributed to most of the flaring activity over the past 24 hours. The solar flaring activity is expected to remain at low levels with possible M-class flares over the next 24 hours.

Koronal Kütle Atılımı

No Earth-directed coronal mass ejections (CMEs) are observed in the available coronagraph imagery over the past 24 hours.

Koronal delikler

The negative polarity coronal hole which first crossed the central meridian on April 07 continues to partly reside there. High speed stream emanating from it might be expected at Earth starting on April 10.

Güneş rüzgarı

Over the past 24 hours the solar wind parameters (ACE and DSCOVR) reflected mildly enhanced conditions under the ongoing influence of a high speed stream. The magnitude of the interplanetary magnetic field (B) remained below 10 nT with a minimum Bz component reaching -7 nT. The solar wind speed was predominantly around 500 km/s with periods reaching 600 km/s. The B field phi angle was entirely in the negative sector (directed towards the Sun). The solar wind conditions are expected to remain enhanced over the next few days under the anticipated influence of an high speed stream.

Jeomanyetizma

The geomagnetic conditions over the past 24 hours were predominantly unsettled to active. Quiet to active geomagnetic conditions are expected for the next 24 hours with chances for isolated minor storms due to ongoing high speed stream arrivals. Quiet to active conditions are expected to continue on April 11 and April 12.

Proton akı seviyeleri

Over the past 24 hours the greater than 10 MeV GOES proton flux has been at nominal levels and is expected to remain so over the next days.

Jeostatik yörüngedeki elektron akıları

The greater than 10 MeV GOES 18 electron fluxes has exceeded the 1000 pfu threshold over the last 24 hours and is expected to exceed the 1000 pfu threshold in the next 24 hours. The 24-hour electron fluence was at moderate levels and is expected to be at the border of moderate to nominal levels in the next 24 hours.
