G2 (Moderate) Geomagnetic Storm Watch Issued for 11 October 2021

[G2_black]
G2 (Moderate) Geomagnetic Storm Watch Issued for 11 October 2021
published: Sunday, October 10, 2021 00:39 UTC

G2 (Moderate) geomagnetic storm conditions are possible on 11 Oct due
to the anticipated arrival of a CME from 09 Oct. G1 (Minor)
geomagnetic storm conditions are possible on 11-12 Oct.

Region 2882 (N17, L=157) produced an M1/2b flare (with Type-II and IV
radio emissions) at 09/0638 UTC, and an associated full-halo CME was
observed in LASCO C2 imagery beginning at 09/0712 UTC. Event analysis
and model output suggest CME arrival around midday on 11 Oct, with
lingering effects persisting into 12 Oct.
