Additional Comments

The coronal mass ejection (CME) seen late on 30-Jun is anticipated to arrive early on 3-Jul resulting in enhanced geomagnetic conditions in the first forecast interval.
Several M-class flares with associated CMEs were observed in the last 24 hours. The origin location of these flares from active regions close to the centre of the solar disk indicates most of them may have an Earth-directed component. Further analysis is required but should these CMEs arrive in relatively quick succession, elevated geomagnetic activity levels are likely to persist.
Overall, ACTIVE conditions are expected with chances of STORM G2 periods.
