Solar wind speed is at 380 km/s with interplanetary magnetic field magnitude of 3 nT. Geomagnetic conditions have been quiet. The northern polar coronal hole as a low latitude extension (reaching up to 20 degrees northern latitude) that could affect the Earth in 48 h, until then quiet conditions can be expected.
