Additional Comments

There have been several coronal mass ejections (CME) observed over the weekend. These all emanated from active region 14485 which is now on the western limb of the solar disc. The bulk of these CMEs may miss Earth, however modelling suggests there are some chances of glancing impacts. CME arrivals are possible during the first and third forecast periods. This could result in ACTIVE periods, with a chance of reaching STORM G1 if any impact is significant.
