G1 (Minor) Geomagnetic Storm Watch 17-18 Jul

G1 (Minor) Geomagnetic Storm Watch 17-18 Jul
published: Wednesday, July 19, 2023 00:20 UTC

A filament eruption associated with a C8 flare from Region 3370 occurred late on 14 Jul. An M2 flare occurred from Region 3363 on 15 Jul with an associated CME off the SW limb. Modeling of the events indicated an arrival on 18 Jul, however there is some uncertainty in the analysis that may see an earlier arrival on the 17th.
