Between 09:00 UT - 16:00 UT the solar wind speed was about 600 km/s.
After 05:00 UT the IMF Bz component gradually decreased, fluctuating between +/-2 nT.
03:00 UT - 09:00 UT: the geomagnetic field reached G1 (Minor) storm levels, due to CIR and the continous effect of the recurrent coronal hole high speed stream (CH HSS).
Between 00:00 UT - 05:00 UT the Bz component of the interplanetary magnetic field (IMF) varied between +10 nT and -11 nT.
The first half of day the IMF Bz component underwent of prolonged and sustained southward direction.
From early period solar wind speeds reached a peak of 425 km/s. Midway through the period solar wind speeds increased to about 620 km/s.
The day began with a total IMF strength at about 15 nT.
The phi angle was positive (away from Sun).
Very low solar activity. No active regions on the visible disk. No Earth-directed coronal mass ejection (CME).
A positive polarity coronal hole (CH) positioned in the Western hemisphere of the Sun produced the high-speed stream (HSS) that enhanced solar wind speeds, and solar wind parameters were indicative of CIR passage.
Strong solar wind speeds persist, sparking bright auroras around the Arctic Circle. Aurora sightings possible from southernmost regions of southern hemisphere.
Aira volcano, Kyushu, Japan (elevation: 1117 m): events occasionally at Minamidake summit crater of Aira Caldera’s Sakurajima volcano. Crater incandescence visible at night. The Alert Level remained at 3 (on a 5-level scale).
Copahue volcano, Central Chile-Argentina border (elevation: 2953 m): thin and diffuse steam plumes containing minor amounts of ash rose and drifted East.
Dukono volcano, Halmahera, Indonesia (elevation: 1229 m): ash plumes rose to altitudes of 2 km and drifted in multiple directions.
Ebeko volcano, Severo-Kurilsk (Paramushir Island), Russia (elevation: 1103 m): about 7 km East of Ebeko explosions generated ash plumes that rose as high as 2 km. The Aviation Color Code remained at Orange..
Great Sitkin volcano, Andreanof Islands, USA (elevation: 1740 m): steam jetting continuously from a small fumarole on the West side within the summit crater, and at one area where snow and ice melted.
Kilauea volcano, Hawaiian Islands, USA (elevation: 1222 m): the lava lake continued to rise.
Sabancaya volcano, Peru (elevation: 5960 m): explosive activity slightly decreased compared to the previous week: an average of 78 explosions per day. Seismicity, dominated by long-period events, with signals indicating emissions. Gas-and-ash plumes rose more than 4 km above the crater rim and drifted 50 km North-east, North and North-west. Thermal anomalies. The public should not to approach the crater within a 12-km radius.
Sinabung volcano, Indonesia (elevation: 2460 m): ash plumes rose more than 3 km and drifted West, West-southwest, East-southeast and East. The Alert Level remained at 4 (on a scale of 1-4). 
Asteroid 2017 WA14 with a diameter of 11 meters passed by the Earth with a velocity of 16.4 km/s at about 76.880 km /0.2 LD (lunar distance)/.
