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 levels. A negative polarity equatorial coronal hole (CH) is spread across the Western hemisphere of the Sun. No Earth directed Coronal Mass Ejections (CMEs) have been detected.

Solar activity is expected to remain at low levels.

The solar wind speed has fluctuated between 525 and 610 km/s (DSCOVR) over the past 24 hours. The total magnetic field strength has fluctuated between 4 nT and 8 nT (DSCOVR). The Bz component has been largely negative, ranging between -12 and +5 nT. Geomagnetic conditions ranged between Kp index 3-5 (NOAA) and local K index 2-5 (Dourbes) over the past 24 hours. The enhanced geomagnetic activity is due to the Earth being under the influence of a HSS associated with the coronal hole that has rotated across the Western hemisphere of the Sun. We can expect to be under the influence of the HSS for the next few days.

Geomagnetic activity is expected to fluctuate around active levels, with a chance of Minor storms.
