Four CMEs Are Heading For Earth - G3 (Strong) Geomagnetic Storm Watch - November 30. 2023.

With 3 CMEs already inbound, the addition of a 4th, full halo CME has prompted SWPC forecasters to upgrade the G2 Watch on 01 Dec to a G3 Watch. This faster-moving halo CME is progged to merge with 2 of the 3 upstream CMEs, all arriving at Earth on 01 Dec. G3 (Strong) conditions are now likely on 01 Dec. G3 Possible Effects Power systems: Voltage corrections may be required, false alarms triggered on some protection devices. Spacecraft operations: Surface charging may occur on satellite components, drag may increase on low-Earth-orbit satellites, and corrections may be needed for orientation problems. Other systems: Intermittent satellite navigation and low-frequency radio navigation problems may occur, HF radio may be intermittent. Auroras may be visible seen as low as Illinois and Oregon (typically 50° geomagnetic lat).
