Solar wind speed is elevated above background levels with speed ranging between 470-550 km/s due to the effect of high-speed streams (HSS) from coronal hole 37 (CH37). No Earth-directed CMEs were evident in the available coronagraph imagery.

There are nine sunspot regions visible on the solar disc with simple to complex magnetic configurations. The solar wind speed is elevated above background levels with speed ranging between 440-510 km/s due to coronal holes influence.
