Bulletin

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 the B class level. There is currently a low-latitude positive-polarity patchy coronal hole approaching the solar limb, a second small coronal hole is currently located in the eastern hemisphere. Solar activity is expected to remain at low levels for the next 24 hours.

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

Over the past 24 hours, the solar wind increased from 450 km/s to 650 km/s peaking around 02:00 UT this morning, there was a small decline before increasing again over the past few hours. The total magnetic field strength has fluctuated between 5 nT and 13 nT. The Bz component fluctuated around 0 nT, ranging between -10 and +10 nT. Geomagnetic conditions ranged between Kp index 2-4 (NOAA) and local K index 2-4 (Dourbes) over the past 24 hours.

Geomagnetic conditions have been enhanced due to the arrival of a high speed stream (HSS) from a small low latitude positive polarity Coronal Hole. Geomagnetic conditions are expected to be enhanced throughout the day.

A small filament eruption occurred in the north-west quadrant of the sun on 20-Nov-2019. 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 on 23-Nov-2019, creating a small enhancement in geomagnetic conditions later in the day.
