The solar activity has been at very low levels over the past 24 hours. The Sun is currently spotless and the X-ray flux remains below B-level. However, a compact bright structure, located at low-latitude near the central meridian, has shown some evidence of activity. There is currently a low-latitude positive-polarity patchy coronal hole located in the Western Hemisphere. Solar activity is expected to remain at low levels for the next 24 hours.

There was a small filament eruption in the north west quadrant of the Sun. The eruption was observed to be moving predominantly to the west in coronagraph imagery. The plane-of-sky speed, as measure by CACTUS, reached around 650 km/s, and although the effects are expected to be small, the CME may arrive around mid day on 23-Nov-2019.

The greater than 10 MeV proton flux was at nominal values.

The solar wind speed has increased from around 300 to 500 km/s over the past 12 hours. The total magnetic field strength has fluctuated between 2 nT and 10 nT. The Bz component fluctuated around 0 nT, ranging between -7 and +8 nT. Geomagnetic conditions ranged between Kp index 0-2 (NOAA) and local K index 0-2 (Dourbes) over the past 24 hours.

Geomagnetic conditions have increased a little (K=2) due to the arrival of a high speed stream from a small low latitude positive polarity Coronal Hole around 21:00 UT yesterday. Geomagnetic conditions are expected to be enhanced at least over the next 24 hours.
