Additional Comments

Solar wind speed has been increasing for the past few hours indicating a slightly earlier than expected connection to the predicted transequatorial coronal hole high speed stream mentioned previously, and this influence should continue throughout the weekend. ACTIVE periods are to be expected with a chance of occasional periods of Minor Storm (most likely G1) for the next few days.
