Additional Comments

Solar wind parameters are at near background levels as previous coronal hole influence has waned. Late during the first forecast interval the Earth is expected to encounter another high speed stream from a recurrent trans equatorial negative polarity coronal hole. This may lead to ACTIVE geomagnetic conditions with possible spells of STORM G1. Effects are likely to continue throughout this forecast period.
