CME Blasted from the Sun on 1 April - Possible Influences on 4 April

CME Blasted from the Sun on 2 April - Possible Influences on 4 April
CME Blasted from the Sun on 1 April - Possible Influences on 4 April
published: Thursday, April 02, 2026 15:09 UTC

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.
