Additional Comments

A Coronal Mass Ejection (CME) associated with a filament lift-off on 8-JUN is estimated to reach Earth in the latter half of first period and into the 2nd. In addition to this, a coronal hole high speed stream could become geoeffective during the second interval, which would further increase the chance of ACTIVE to STORM G2 periods.
