Bulletin

Over the past 24 hours solar activity has been low. No significant flares have been recorded. No significant Active Regions (AR) or filament channels are present on the solar disk. The greater-than 10 MeV proton flux was at nominal values. A negative polarity equatorial coronal hole (CH) has reached W45S15.

Solar activity is expected to remain at low levels.

The solar wind speed has fluctuated between 320 and 340 km/s (DSCOVR) over the past 24 hours. The total magnetic field strength has fluctuated around 4 nT (DSCOVR). The Bz component fluctuated around 0 nT, ranging between -2 and +4 nT. Geomagnetic conditions ranged between Kp index 0-1 (NOAA) and local K index 0-3 (Dourbes) over the past 24 hours. A negative polarity coronal hole is currently positioned near W45S15 in the Western hemisphere of the Sun and the associated co-rotating interaction region (CIR) and high-speed stream (HSS) may enhance solar wind speeds towards the end of the day and for the next few days, as a consequence geomagnetic activity is expected to reach to active conditions.

Geomagnetic conditions are expected to be unsettled and possibly active from later today / early tomorrow.
