between 04:30 UT - 05:30 UT solar wind speeds increased and reached a peak of 550 km/s, due to the influence of a large coronal hole with a highly irregular shape, and its positive polarity CH HSS.
Over the day the Bz component of the IMF ranged between - 10 nT to 8 nT;
between 10 UT and 14 UT with a prolonged southward excursion up to -7 -9 nT.

The Bz component of the IMF has ranged between +/-8 nT;
at 06 UT starting with a more disturbed period;

By 12 UT the solar wind speed increased to reach the maximum of about 505 km/s, due to the effect of the recurrent coronal hole high speed stream,
then, for the remainder of the UT day it became variable between 420-510 km/s.
