A coronal mass ejection (CME) as part of a filament eruption occurred on 1 April. Initial analyses of the CME suggests primarily an arrival just ahead and mostly north of Earth’s orbit. However, some outlier model runs hint at some glancing influences by 4 April. SWPC forecasters continue to evaluate this CME and will make and possible geomagnetic storm Watch decisions as the forecast becomes finalized.
