The solar flaring activity was low over the past 24 hours. The large flare was a C3.8 observed on the east limb, from a region that is about to rotate to the front disc side. 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 from this new region.
No Earth directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph imagery.
The solar wind conditions are under the influence of the high- speed stream from the negative polarity equatorial coronal hole (that crossed the central meridian on April 01). The interplanetary magnetic field phi turned in the negative sector (directed towards the Sun). The solar wind speed ranging between 405 km/s and 558 km/s. The total interplanetary magnetic field reached values around 10 nT and the Bz component reached values up to -7.7 nT. The solar wind conditions are expected to be enhanced on April 05 and then to return to slow solar wind speed.
Geomagnetic conditions were unsettled to active (NOAA Kp 2-4 and Local K Bel 2-4) in response of the high-speed stream from the negative polarity equatorial coronal hole (that crossed the central meridian on April 01). Geomagnetic conditions are expected to be at unsettled with possible active conditions on April 05.
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.
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.

Op basis van de huidige parameters is er in de nabije toekomst een beperkte kans op poollicht op de volgende locaties van de hoge breedtegraad
Gillam, MB, Yellowknife, NTOm ook bereikbaar te blijven bij grote poollichtkansen hebben we een zware server nodig die alle bezoekers aankan. Doneer en steun dit project zodat we online blijven en je geen enkele poollichtkans mist!
