G1 Minor Storm levels likely on 25-27 Jan 2024
published: Saturday, January 27, 2024 13:37 UTC

Additional CMEs erupted from the Sun on 23 Jan 2024. Analysis indicated that at least part of these CMEs could come close enough to Earth to raise geomagnetic storm conditions to the G1-Minor level on 27 Jan. This extends the Watch period from 25 Jan through 27 Jan. As with the previous post, higher storm levels are possible if more of a direct impact and/or stronger connection with Earth's magnetic field lines occurs.
