Additional Comments

Solar wind speed remains elevated due to ongoing coronal hole influence, but may be starting to show the first signs of declining although this may take several days to return to background levels. A risk of an occasional ACTIVE period remains for the next couple of days due to the effects of this high speed stream.
We cannot rule out the slight chance that we may yet see a weak glance from a CME on the 18th, however any impact on geomagnetic activity is unlikely to be significant should it arrive during day one.
An M-class flare has been observed in the past hour, possibly associated with a filament eruption in the southeast of the solar disk, which may have an associated CME. Further analysis is required when more data becomes available to determine if there is any Earth-directed component to any CME.
