Solar activity has been quiet over the past 24 hours. The X-ray flux remained at background levels, and the visible solar disc is spotless. EUV imagery reveals a simple magnetic structure in the Eastern hemisphere approaching the central meridian, but appears stable in magnetogram observations. Solar activity is expected to remain at low levels for the next 24 hours.

No Earth directed Coronal Mass Ejections (CME) have been detected in the available coronagraph imagery over the past 24 hours. However, there is evidence of a small Earth directed CME observed in STEREO COR2 observations, emerging on 03-Jun-2019, with a speed of approximately 210 km/s, (STEREO A is located near the L5 point). The CME was not visible from LASCO coronagraph imagery (Earth orientated). The eruption is anticipated to interact with the Earth system late on 07-Jun-2019, but the effects are expected to be small.

The greater than 10 MeV solar protons flux remained at nominal levels over the past 24 hours and is expected to remain so.

The solar wind speed has fluctuated between 320 and 360 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 4.0 and 8.0 nT. The Bz component fluctuated around 0 nT, between -7.0 and 3.0 nT. Geomagnetic conditions fluctuated between Kp index 1-2 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. The Earth is currently under the influence of a slow solar wind stream. A small CME, observed in STEREO imagery on 03-Jun-2019, with a speed of approximately 210 km/s, is anticipated to interact with the Earth system late on 07-Jun-2019, but the effects are expected to be small. Geomagnetic conditions are expected to be quiet with a small possibility of unsettled conditions.
