G1 (Minor) Watch Continues for 20 February, 2023

G1 Watch 20 Feb, 2023
G1 (Minor) Watch Continues for 20 February, 2023
published: Tuesday, February 21, 2023 21:35 UTC

A G1 (Minor) storm watch continues for 20 February, 2023 due to CME arrival and passage. The anticipated CME associated with the X2 flare on 17 February arrived at Earth early 20 February, at 5:39 am EST (1039 UTC); shortly after being detected as a shock arrival at the DSCOVR spacecraft at 4:52 am EST (0952 UTC). CME passage continues and should the total interplanetary magnetic field strength become more favorable for connection with Earth's magnetosphere, G1 storm conditions are possible.
