Quiet solar conditions were reported with not a single flare occurring and the X-ray flux remained below B level. Both active regions on disk are relatively simple (McIntosh: Hax; Mag.Type: Alpha) and quiet. The X-ray flux is expected to remain below C level. Proton flux levels were at background values and are expected to remain so. No Earth directed CME's were recorded in coronagraph data.

Solar wind remained initially nominal until a weak shock at 7:41UT occurred in the interplanetary Solar wind as measured at L1 by the DSCOVR spacecraft. Solar wind speed initially increased only slightly from around 360 km/s to around 380km/s with also a moderate increase in total magnetic field from around 4nT to 6.5nT. But this was followed by the transition into a positive polarity sector as indicated by the shift in phi angle around 10:30UT after which solar wind speed started a steady ascent to 450 km/s presently and total magnetic field reached up to 15nT. The Bz component of the magnetic field is variable but with some periods of sustained negative values down to -10nT. The perturbed conditions are a result of a high speed stream from the coronal hole in the northern hemisphere. Perturbed solar wind conditions are expected to continue with solar wind speed steadily increasing over the next 24-48 hours before starting to subside. Geomagnetic conditions were quiet to unsettled. Geomagnetic conditions are expected to become unsettled to active with also periods of minor geomagnetic storming expected over the next 24-48h.
