Slunečně aktivní oblasti a vzplanutí

The solar flaring activity was very low over the past 24 hours. The X-ray flux is at B-class levels. Few sunspots groups are visible on the disc. However they remain quiet. The solar flaring activity is expected to be at low levels over the next 24 hours, with possible C-class flares.

Vyhazování koronální hmoty

No Earth directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph imagery.

Koronální díra

A small positive polarity high-latitude south coronal hole is crossing the central meridian on April 07.

Solární bouře

The solar wind conditions underwent very mild influence of the high-speed stream from the negative polarity equatorial coronal hole (that crossed the central meridian on April 01). The conditions are now returning to the slow solar wind regime. The interplanetary magnetic field phi is in the negative sector (directed towards the Sun). The solar wind speed ranging between 400 km/s and 500 km/s. The total interplanetary magnetic field was below 6.5 nT and the Bz component fluctuated between -4.7 nT and 5.5 nT. The solar wind conditions are expected to continue its return to the slow solar wind regime on April 07 and April 08.

Geomagnetismus

Geomagnetic conditions were quiet (NOAA Kp 1-2 and Local K Bel 1-2) and expected to remain quiet on April 07 and 08.

Úrovně protonového toku

Over the past 24 hours, the greater than 10 MeV GOES proton flux was below the 10 pfu threshold and is expected to remain below this threshold for the next 24 hours.

Elektronové toky na geostacionární oběžné dráze

The greater than 2 MeV electron flux remained below the 1000 pfu threshold as measured by GOES 16. It is expected to remain below this threshold over the next days. The 24-hour electron fluence was at nominal levels. The electron fluence is expected to be at nominal levels over the next day.
