Additional Comments

The first of the expected coronal mass ejections (CME) may have arrived yesterday giving a weak response in the solar wind. A second CME may arrive in the first forecast interval bringing a chance of ACTIVE to STORM G1 periods.
Towards the end of the third forecast period we may start to see effects from the next high-speed solar wind stream from a coronal hole.
