THIS SUPERSEDES ANY/ALL PRIOR WATCHES IN EFFECT
Comment: A CME that left the Sun on 28 June is anticipated to arrive at Earth early to mid UTC day on 02 July and will likely result in G1 (Minor) geomagnetic storming. Lingering CME effects will likely continue into 03 July causing continued, isolated minor storming periods.
Induced Currents - Weak power grid fluctuations can occur.
Spacecraft - Minor impact on satellite operations possible.
Aurora - Aurora may be visible at high latitudes, i.e., northern tier of the U.S. such as northern Michigan and Maine.
