G2 geomagnetic storm watch

Wednesday, 3 November 2021 15:40 UTC

Yesterday's M1.7 full halo coronal mass ejection stands out in this model run (see the tweet below) and is expected to arrive tomorrow at about 6 UTC. The M1.7 coronal mass ejection was a gorgeous asymmetrical full halo coronal mass ejection and it is expected to gobble up any other weaker eruptions that might be on the Sun-Earth line as well. The NOAA SWPC also upgraded the anticipated storm conditions to the moderate G2 (Kp6) geomagnetic storm level.

The SIDC has also revised their forecast today with the help of additional coronagraph data from STEREO-A COR 2 and now expects an impact tomorrow from 12 UTC onwards.

The NOAA SWPC has updated their WSA-ENLIL solar wind model with a new run that includes three coronal mass ejections. The M1.7 full halo CME stands out and is expected to arrive tomorrow at 6 UTC.
