Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was at low levels over the past 24 hours with only C-class flared observed. A total of 9 numbered sunspot groups were identified on the visible solar disk. The strongest activity was a C5.3 flare (SIDC Flare 4046) peaking on April 07 at 15:36 UTC. It was produced by SIDC Sunspot Group 461 (NOAA Active Region 4048), which has exhibited significant flux emergence and is classified as magnetic type beta-gamma. This regions was responsible for most of the observed flaring activity over the past 24 hours. The solar flaring activity is expected to be at low to moderate levels over the next 24 hours with likely M-class flares.

Koronalny wyrzut masy

A faint and narrow filament eruption was detected near the disc center, but it does not seem to be associated to an Earth- directed coronal mass ejection (CME). No other Earth-directed CMEs are observed in the available coronagraph imagery.

Dziury koronalne

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

Wiatr słoneczny

Over the past 24 hours the solar wind parameters (ACE and DSCOVR) exhibited small enhancements possibly reflecting an anticipating high speed stream. The interplanetary magnetic field (B) reached a maximum value of 12 nT and a minimum Bz of -9.6 nT. The solar wind speed was smoothly varying between 450 km/s and 540 km/s. The B field phi angle was predominantly in the negative sector (directed towards the Sun). The solar wind conditions are expected to remain under the influence of a high speed stream over the next 24 hours with a new possible arrival expected on April 10.

Geomagnetyzm

The geomagnetic conditions over the past 24 hours were quiet to active. Quiet to active geomagnetic conditions are expected for the next several days.

Poziomy przepływu protonów

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.

Strumienie elektronów na orbicie geostacjonarnej

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