Additional Comments

Elevated solar wind speed from the large southern coronal hole continue to influence Earth. Currently the effects are waning, but further enhancements are possible over the forecast period as this coronal hole rotates around the solar disc. There is also a slight chance of a minor enhancement in the solar wind during the 23rd due to a glancing blow from a filament eruption, although this is low-confidence.
