The solar flaring activity over the past 24 hours was at low levels with a single low C-class flare produced by the largest active region on the visible solar disk, NOAA 3141 (beta). The region has pronounced leading and trailing spots, but its complexity remained unchanged and most of its flaring activity was at very low levels. NOAA 3135 (beta) and NOAA 3135 (beta) have remained mostly unchanged and inactive. All other active regions are simple with underlying magnetic type alpha and have either exhibited signs of decay or remained stable. The flaring activity over the next 24 hours is expected to be at very low to low levels.

No Earth-directed coronal mass ejections CMEs were detected in the available coronagraph imagery over the past 24 hours.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain so in the next 24 hours. The greater than 2 MeV electron flux has been well above the1000 pfu threshold over the past 24 hours and is expected to remain mostly above the 1000 pfu threshold over the next 24 hours. The 24h electron fluence was at moderate to high levels and might reach high levels over the next 24 hours.

Over the past 24 hours the solar wind parameters (ACE and DSCOVR) followed a declining trend, recovering from the waning influence of a high speed stream (HSS). The solar wind velocity was in the range of 388 km/s to 532 km/s. The interplanetary magnetic field was weak with a maximum value of 4.6 nT and a minimum Bz component of -3.7 nT. The magnetic field remained predominantly in the positive sector (directed away from the Sun). The solar wind velocity and temperature are expected to continue their recover towards background slow solar wind conditions today and be mostly at slow solar wind conditions on Nov 7th. Slightly enhanced solar wind conditions might be expected late on Nov 7th and Nov 8th with the possible arrival of another HSS from a small and narrow positive polarity coronal hole.

The geomagnetic conditions over the past 24 hours were globally quiet and locally in Belgium quiet with an isolated unsettled period between 15 UTC and 17 UTC on Nov 5th. Mostly quiet geomagnetic conditions are expected for the next 24 hours with chances for isolated unsettled periods.
