Additional Comments

Solar wind has returned to mostly background levels after the stormy conditions last weekend.
The coronal mass ejection (CME) observed in the afternoon on 10-Oct could give us a glancing blow during the first forecast interval. The CME effects could combine with the expected arrival of a high speed stream from centrally located coronal holes, increasing the chances of further ACTIVE and STORM G1/G2 periods.
Time of forecast: 12 Oct 2026
