G4 (Severe) Geomagnetic Storm Watch for 20 January UTC-Day
- rediguanayum 9mo agoA G4 (Severe) geomagnetic storm watch is in effect for the 20 January UTC-day due to Earth-arrival of a coronal mass ejection (CME). The CME blasted from the Sun on 18 Jan, in association with an energetic R3 (Strong) solar flare from a sunspot region near center-disk, and is anticipated to arrive at Earth as early as late 19 Jan EST to early 20 Jan. While the G4 Watch is out for the 20 Jan UTC-day, geomagnetic storm levels could range from G1-G3 (Minor-Moderate) upon CME arrival later on 19 Jan EST.
