The SIDC is part of the Royal Observatory of Belgium and a partner in the Solar Terrestrial Center of Excellence (STCE).


Solar activity was at very low levels. The solar disk was spotless. No
coronal mass ejections (CME) were observed over the last 24 hours. The
greater than 10 MeV proton flux was at nominal values. A diffuse and
fragmented negative polarity equatorial coronal hole (CH) is transiting the
central meridian.

Solar activity is expected to remain at very low levels.

The earth environment is exiting the wind stream from the positive polarity
CH. Solar wind decreased from about 475 km/s to its current 380 km/s
(DSCOVR). Bz varied mostly between -4 and +3 nT. The interplanetary
magnetic field was mostly directed away from the Sun (positive sector).
Quiet geomagnetic conditions were observed. 
Mostly quiet geomagnetic conditions are expected. The arrival of the wind
streams associated with the negative polarity CHs, currently expected for
17 June, may drive geomagnetic activity to active levels, with a minor
storming episode not excluded.
