Solar X-ray flux remained below B class levels throughout the period. The Solar disk is spotless and X-ray flux is expected to remain at or below background levels.

There are currently no SoHO-LASCO coronagraph observations available, HAO- kCOR ground-based coronagraph observations (around 18:00 UT on 22-Sep-2019) combined with STEREO-A COR coronagraph and SDO-AIA EUV observations indicate no Earth-directed CMEs (Coronal Mass Ejection) were produced. Without LASCO data to corroborate the absence of a CME, these observations should be treated with caution, with the small possibility of an unobserved Earth directed CME having been produced.

Proton levels were at background values and are expected to remain so.

The solar wind speed has been slowly decreasing from around 350 to 300 km/s over the past 24 hours. The total magnetic field strength has fluctuated around 5 nT. The Bz component has been largely positive, fluctuating between -2 and 5 nT. Geomagnetic conditions ranged between Kp index 0-1 (NOAA) and local K index 0-3 (Dourbes) over the past 24 hours.

Solar wind conditions are expected to increase at the end of the day, and then become enhanced over the following 24 hours due to a high speed stream (HSS) from a recurrent equatorial coronal hole. The solar wind speed is anticipated to reach speeds exceeding 500 km/s.

Geomagnetic conditions are expected to become unsettled around the end of the day, with some active periods due to HSS solar wind enhancements.
