COMMENT: 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.
