We are now in G5 territory! Both NOAA and the GFZ in Potsdam are reporting Kp index at 9 (G5). GFZ is the source of the index. This is happening far earlier than predicted. G5 conditions were first observed at Earth at 6:54 p.m. EDT (22:54 UTC).
Let's hope we get a terrific light show tonight and nothing more 🤞.
