Additional Comments

Solar wind parameters indicate a possible, weaker than expected, glance from the 10th Oct coronal mass ejection (CME) last night.
Additional CMEs associated with filament eruptions were observed between 11th-12th Oct, with most of the ejecta directed to the south-east. Further glancing impacts are anticipated during the first and second forecast interval.
Coronal hole high speed stream arrival is expected in the next 24 hours, which in combination with potential CME effects could increase the chances of STORM G1 and brief STORM G2 periods.
