The solar flaring activity was low over the past 24 hours. The large flare was a C2.0 observed from the active region NOAA 3630. 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.
No Earth directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph imagery.
A small negative polarity equatorial coronal hole has crossed the central meridian on April 05.
The solar wind conditions undergo mild 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 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 reached values around 9.5 nT and the Bz component reached values up to -7.6 nT. The high-speed stream associated to the small negative polarity equatorial coronal hole may contribute to the solar wind enhancement in the next day. The solar wind conditions are expected to remain slightly enhanced on April 06 and April 07.
Geomagnetic conditions were unsettled (NOAA Kp 2-3 and Local K Bel 1-2) 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 conditions on April 06 and 07.
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.
Today's estimated international sunspot number (ISN): 081, based on 14 stations.
