Additional Comments

Solar wind parameters remain elevated following yesterday's arrival of the coronal mass ejection (CME) from 26-Jun. Further enhancement is expected today due to a potential second arrival of the weak CME from 27-Jun.
Another CME associated with an X-class flare was observed around 21:00UT on 30-Jun. Although further analysis is required, the origin location close to the centre of the solar disc suggests a possible Earth-directed component with predicted arrival on 03-Jul.
Overall ACTIVE geomagnetic conditions are anticipated, with chances of STORM G2 periods.
