THIS SUPERSEDES ANY/ALL PRIOR WATCHES IN EFFECT
Comment: G1 (Minor) geomagnetic storming is likely on 23 Jul due to recurrent, negative polarity coronal hole high speed stream effects.
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.
