COMMENT: We had active geomagnetic conditions because of the Y-shaped
equatorial coronal hole. The strongest equatorial part of the hole
passed already. We are now under the influence of the fast wind
emanating of the two last parts of the hole. One part is in the northern
hemisphere, the other in the southern hemisphere. The solar wind speed
increased up to 750 km/s. The magnetic field carried by the solar wind
is limited in strength. We except unsettled conditions sporadic active
periods are possible.
